Some Markov chain Monte Carlo theory4. The Bayesian linear model 12. Utilitarian Markov chain Monte Carlo5. The Bayesian prior 13. Advanced Markov chain Monte Carlo6. Assessing model quality Appendix A: Generalized linear model review7. Bayesian hypothesis testing and the Bayes’ factor Appendix B: Common probability distributions8. Monte Carlo methods Appendix C: Introduction to the BUGS language

Readership: The book will be very suitable for students of social science, for example politicalscience, who wish to analyze data using modern Bayesian methods.

One is tempted to think of this book as essentially consisting of two parts, Chapters 1 through 7on basics of Bayesian Analysis, and Chapters 8 through 13 on MCMC and Hierarchical BayesianAnalysis. However, this simplistic view is not wholly correct, since MCMC calculations are usedthroughout the first six chapters at least by way of illustration. But this conceptual division intotwo parts would help a reader as well as a teacher using it as a text.

Chapter 1 is a beautifully written introduction to the whole subject of Bayesian Analysis.Along with some more material from the other chapters, it could serve as a crash course onBayesian Analysis. I have a small caveat about Section 1.7, where the scientific aspects of SocialScience are discussed. There are three more issues that could have been discussed here: (1)the difficulties of replicability, (2) the hazards of trying to model human behavior (collective orindividual), and (3) the near impossibility of controlled experiments, where some factors leadingto variation are controlled at fixed levels.

Chapter 2 provides the first of several interesting examples, mostly from Political Science.This one concerns the duration of cabinets of some chosen European countries. The posterioranalysis is simple but interesting.

Examples in the later chapters include French Labor Strikes, Ancient Chinese Conflicts, andthe ongoing Afghan war, where the analysis identifies the point of time when the Taliban beganto wrest the initiative from Afghan Government and its Allies.

Chapter 7 on Bayesian Testing is somewhat weak compared with other chapters, due in partto the lack of consensus among Bayesians about sharp nulls. Gill uses Bayes Factors but notfor sharp nulls. He tries to avoid testing sharp nulls by reporting a credibility interval for theparameter, but then notes if the interval contains zero or not, which is a form of testing advocated

by some Bayesians. He wavers between dismissing sharp nulls completely useless and helplesslyusing them in bread and butter problems of variable selection in linear and generalized linearmodels.

The second part has a lot of material on MCMC, some of which seems a bit too technicaland not strictly relevant for potential users of the book. But they could serve a useful purpose ifsome readers are willing to supplement this material with more standard texts on MCMC likeCasella and Robert. Though the importance of Hierarchical Bayesian Analysis and MCMC isexplained at different places, the chapter on Hierarchical Bayes is good but surprisingly short.Hopefully, it will grow in future chapters.

The book has a few typos or what appear to be typos. For example, the Jeffreys prior isdefined without a mention of a determinant and it isn’t easy to realize we are looking at adeterminant, not a matrix. The reference list is carefully compiled, it will be very useful fora well-motivated reader. Altogether it is a very readable book, based on solid scholarship andwritten with conviction, gusto, and a sense of fun.

landmarks Appendix B: Packages used in this text5. Statistical analysis of outlines

Readership: Beginning graduate students, and researchers and graduate students in any disciplineneeding to explore and analyze morphometric data.

Chapter 1 begins with a short introduction to geometric morphometrics. A key idea is landmark,a position that is comparable across different organisms or other objects of study. For biologicalorganisms, it should reflect homology arising, usually, from a similar developmental origin. Themethodologies that are described here build on the pioneering work of D’Arcy Thompson. Shapesare mapped to a grid, with changes between objects described by mathematical transformations.Simple changes may for example include one or more of distending, flattening and shearing. Anintroduction to the R system occupies the major part of the chapter.

Chapter 2 begins with a brief section on collecting and organizing morphometric data, thenmoves on to data acquisition and manipulation with the R system. The final two sections discussmissing values and measurement error issues.

Chapter 3 is a very brief introduction to the exploratory analysis of multivariate data such asare used in morphometrics. It ends with brief overviews of principal components analysis, lineardiscriminant analysis, MANOVA, clustering, and related techniques.

SHORT BOOK REVIEWS 303

Chapter 4 is an account of methods for describing and modeling shape changes, based onthe use of homologous landmarks. It starts with the truss network approach of Strauss andBookstein. These are somewhat akin to the truss networks that may be used in the constructionof, for example, bridges. Remaining sections describe Procrustes and other superimpositionmethods, the use of thin-plate splines, distance matrix analysis, and angle-based methods.

Chapter 5 has sections on splines and other curve-fitting methods, Fourier analysis, andeigenshape analysis.

Chapter 6 describes methods for visualizing shape change. Largely, this is a continuationof Chapter 3. An interesting challenge is to combine morphometric data with phylogeneticinformation that makes evolutionary connections.

Chapter 7 extends discussion of the use of R; there are sections on simulation, variousprogramming issues, and interfaces to other systems.

This is a highly useful guide to the literature and to the range of methodologies. A valuablefeature is the inclusion of R code that shows how to implement the methods that are described.The quality of the writing and overview is, in places, uneven.

Table of contents

1. Basic models 6. Natural selection2. Estimation and hypothesis testing 7. Diffusion processes3. Recombination 8. Multidimensional diffusions4. Population complications 9. Genome rearrangement5. Stepping stone model

Readership: All readers interested in Population Genetics in a broad sense.

This is a beautifully written book by a distinguished probabilist on what used to be calledPopulation Genetics, and now, more appropriately, is called DNA Sequence Evolution. This is asecond edition, but the second edition has so much new material that it’s almost a new book.

The preface provides good summary of what the book does in respect of DNA SequenceEvolution. Chapter 1 deals with the classical Fisher-Wright model, based on statistical geneticsrather than DNA sequence, and Kimura’s hypothesis of neutral mutations. This is like the nullhypothesis of Population Genetics and Chapter 2 shows how this can be tested. Chapters 3through 6 provide alternative models including various forms of natural selection via mutation.Chapters 7 and 8 replace the discrete time models by one dimensional and multidimensional(continuous time) diffusion models. Chapter 9 deals with “evolution of whole genomes”, whichis of very recent vintage, but this chapter is also “the least changed” from the first edition.

The book is very clearly and elegantly written. I enjoyed reading what I sampled, namely,Chapter 1 and parts of Chapters 2, 7, 8, and 9. While the book is very well written and accessibleto readers with a minimal background in Biology and some knowledge of basic probabilitytheory and Markov processes, the material is tough for anyone who wants to read all theproofs carefully. Applications of probability theory includes local times, Markov processes withboundaries, Green’s function, and of course many innovative, interesting calculations.

It is strongly recommended to all readers interested in Population Genetics in a broad sense.Moreover parts of it can be used for other courses. For example Chapter 1 can provide additionalrelated material to a Bayesian course that covers Dirichlet processes, and Chapter 7 could be aninteresting supplement to a course on diffusion.

No matter how good a book is, a reader will have a couple of unfulfilled wishes. Mine arethese: It would be nice to have a non-technical last chapter that summarizes the overview of thoseaspects of the subject that were modeled, tested, and confirmed, and those that are in doubt. Theoriginal goal of Fisher, and probably Wright, was to confirm Darwin’s theory of evolution andnatural selection using Mendelian statistical genetics. How is that confirmation viewed today?Secondly, since the book abounds with beautiful theorems and proofs, a short non-technicalguide to the more important ones, as the preface covers the biological contents, would begood.

Readership: Workers in Medical Statistics, Epidemiologists.

A randomised controlled trial is the traditional gold-standard design in what has come to beknown as evidence-based medicine. The participants or units are randomly allocated to thedifferent conditions or treatments under study. In a cluster randomised trial (CRT) the units areso allocated in groups. These groups, or clusters, can be geographical (look for the ‘fried eggdesign’), institutional (schools, organisations, etc.), or even individual people (the units of thecluster being teeth, for example).

The authors point out that the CRT is relatively new and that, although the topic is covered herepretty comprehensively, it is still an active research area. It’s difficult to think of any importantissue or aspect that is not discussed here, and at length and in depth.

The book is divided into four parts: Part A discusses when and why one should use a CRT;Part B shows how to do it; Part C describes data analyses; Part D rounds up some related issues.In particular, Part C shows how the clustering gives rise to specialised statistics. The ‘problem’is correlation, which results from within- and between-cluster variation: in fact, the so-calledintraclass correlation is just based on a ratio of these.

There is no heavy mathematics so the material is accessible to a wide range of readers. Theemphasis is on practical applications, reflecting in some degree the authors’ own work. Particularattention is given to rates and proportions, such data frequently arising in epidemiology. Thestatistical analyses are performed using the ‘Stata’ package, and data are available on thepublisher’s web site.

Target readership areas: Computational statistics, adaptive signal processing, adaptive controlengineering, communication networks, neural networks, reinforcement learning.

The author notes in his Preface that Stochastic Approximation was born in the Statistics literaturebut has grown up in Electrical Engineering. However, it is by no means fully grown: itsdevelopment continues apace in a wide variety of settings – see the readership areas listedabove. The author describes his book as ‘a compact account of the highlights’ of the subjectfor ‘an interested, mathematically-literate reader’. Here, mathematically-literate entails a goodworking knowledge of real analysis and ordinary differential equations, together with familiaritywith probability theory up to martingales.

There are two broad approaches to the subject: statisticians (more precisely, probabilists) comefrom a background in martingale convergence behaviour, whereas (mathematically-inclined)engineers travel a route through ordinary differential equations associated with dynamicalsystems. As suggested by the subtitle of the book, the latter approach is predominant here.

The first chapter gives a gentle, very readable, introduction to the essence of the subject. Butthen, in chapters 2 to 9, one has to get down to work: the material is quite demanding, muchof it comprising theorems and proofs. Chapter 10 describes some applications and Chapter 11contains some appendices on mathematical prerequisites.

There is no hiding the fact that this is a tough subject, not one for the lazy-minded. But, it’sclearly a vital core subject, central to a variety of important applications. So, ‘an interested,mathematically-literate reader’ looking for a rewarding area of work could do a lot worse thanstudy ‘this little book’, as the author modestly refers to it.

systems E. Miscellaneous

Readership: Applied probabilists, theoretically-oriented statisticians, research workers andstudents.

Semi-Markov Processes (or Markov Renewal Processes), combining Markov Processes andRenewal Theory, were introduced in the mid-1950s. There followed much research, mainly in acontinuous-time framework. This book focuses on the less well-developed discrete-time version,a hybrid of Markov Chains and Recurrent Events (as discrete-time renewal is called in FellerVolume I). In the last chapter a further layer is added in which the semi-Markov chain is hidden(unobserved) but gives rise to a process, via a probability law, that is observed.

There are six chapters: in the first the scene is set (notation, definitions, etc.) and an overviewof the subsequent chapters is given; there follows discrete-time renewal theory (Chapter 2) andsemi-Markov chains (Chapter 3); Chapter 4 addresses non-parametric estimation, essentiallyestimates based on proportions of observed events, Chapter 5 covers reliability aspects ofsuch systems, and Chapter 6 introduces the hidden version and its non-parametric maximumlikelihood estimation. There are also some appendices covering certain technical results.

Overall, this is a stimulating book. As it says, the discrete-time framework has been underusedin the past in view of the fact that much real data in practice (I would even say most) is recordedin discrete time. Also, the applications listed, particularly the DNA sequencing, are importantand timely.

Readership: Psychologists and Bayesian statisticians.

Informative hypotheses are best illustrated by typical examples, e.g.,

H1 : μ1 > μ2 > μ3

or

H2 : {μ1 ≈ μ2} > μ3.

The first statement is clear, the second asserts that μ1 and μ2 are nearly equal and both are greaterthan μ3. In applications μ’s are typically means but could be other parameters of interest. Thesehypotheses are being used by psychologists to have more meaningful hypotheses than the usualversions based on a somewhat artificial null hypothesis and its negation. In that approach eachof the above two hypotheses would lead to more than one null and alternative.

Along with this new formulation, the authors of articles in this volume rely on the Bayesianparadigm both because of its logical and philosophical attractions and the ease with which suchinequality constrained “informative” hypotheses can be tested in this paradigm.

SHORT BOOK REVIEWS 309

This book has been very imaginatively planned and anchored around analysis of challengingproblems of (Clinical) Psychology. Not only the analyses but the design of experiments and thevariables measured are very interesting.

The first problem, commonly known as Multiple Personality Disorder, is that of a person whoclaims to have two or more separate identities, each of which forgets what the other does. Isthis real or simulated? In addition to the patients, there are three control groups, namely, truecontrols, simulators of amnesia, and true amnesiacs. The hypothesis of interest is H1: μcon >

{μamn = μpat} > μsim, where μ = true mean of a memory score. H1 implies the disorder isgenuine. The other hypothesis H2 is that μcon > μamn > {μpat = μsim}, i.e., the disorder issimulated by the patients.

The second problem concerns the effect of “peer evaluation on mood in children high andlow in depression.” The third is about “coping with loss: the influence of gender, kinship andthe time from loss.”

The problems of inequality constrained hypotheses are studied through Bayes factors. Thereis also a study of robustness of the conclusions with respect to choice of priors. Bayesian readerswill recognize at least two well known Bayesian analysts among the authors.

A final part, namely Part IV of the book, sums up and evaluates these analyses by psychologistsand statisticians. There are three evaluations in this part, one by a psychologist, one by astatistician and one by a philosopher.

This is an excellent book for psychologists and Bayesian statisticians. Strongly recommendedfor both categories of readers.

pages 5–13. Did you know (p. 58) that the late well-known statistician I. J. (Jack) Good was AlanTuring’s chief statistical assistant at the U.K. code-breakers’ Bletchly Park in 1942? Well knownchess masters C. H. O’D Alexander, P. S. Milner-Barry and Harry Golombek were also there(see p. 58). I could go on, but you get the idea! This would be a great gift for any statistician ormathematician.

Introduction 4. Defining multilevel latent variables1. Investigating organizational structures, processes, 5. Multilevel structural equation models

and outcomes 6. Multilevel longitudinal analysis2. Development of multilevel modeling techniques 7. Multilevel models with categorical variables3. Multilevel regression models

Readership: Graduate or advanced undergraduate students as well as researchers for example inthe organizational, educational, behavioral, and social sciences.

This book presents an applied approach to the use of multilevel modeling in exploring varioustypes of hierarchical data structures. A basic knowledge of data analysis and univariate statisticsis assumed.

Since the first edition (2000) of the book, there have been lots of advances both in the theoryand the software. The book covers the newest and most important achievements, but at the sametime gives a nice summary of the historical development of multilevel models. It also addressessome issues for further consideration.

The first four chapters challenge the reader to think about the complexity of multilevel datastructures compared to the usual or traditional single-level data structures and their analysis.Two software programs, HLM and Mplus, are briefly introduced.

The last four chapters present more complex multilevel modeling schemes, including structuralequation models using latent variables, analyzing change processes via longitudinal analysisand utilizing categorical variables e.g. by mixture models. All these approaches are shown tohave much in common, although their paths of development have varied considerably. In thisbook, the approaches are brought under a unified framework for exploring hierarchical datastructures.

The examples worked through using the software mentioned above and with real data areessential and help to understand the points made in the text. The text itself is very readable andthe level of the mathematical detail is not high. Unfortunately the software programs seem abit clumsy and old-fashioned (both input and output). It may be understood as a current stateof the scientific development, and also as a historical tradition, but it would be important to

Readership: Statistics students at the upper-undergraduate and beginning-graduate levels,applied statisticians, industrial practitioners, and researchers.

This is the Second Edition of the book by Charles E. McCulloch and Shayle R. Searle, publishedin 2001. “This text is to be highly recommended as one that provides a modern perspective onfitting models to data.” – That was the first sentence of Philip Prescott’s review on the FirstEdition on these ISR Short Book Reviews in 2001. It is a pleasure to agree with this commentand welcome the new revised edition, with the third coauthor John M. Neuhaus.

The very readable style and peaceful and patient explanation of the details and leadingprinciples, is nicely present in this book. The Second Edition has three new chapters andnumerous new and updated examples, and in addition the rest of the book has been lightlyrevised. Citing the Preface: “As before, the emphasis is on the applications of these models andthe assumptions necessary for valid inference. The focus is not on the details of data analysis northe use of statistical software, though we do briefly mention some examples.” All in all, being agreat Shayle Searle book fan, I am happy to keep this book near my desk and recommend it tomy students.

1. Biostatistics and microbiology: Introduction 5. Regression and correlation analysis2. One-sample tests 6. Qualitative data analysis3. Two sample statistical tests, normal distribution 7. Nonparametric statistical methods4. Analysis of variance Appendix: Tables of mathematical values

Readership: Microbiologists who wish to carry out a statistical analysis of their own data.

This is a well-written elementary introduction to common statistical tests, estimates, andconfidence intervals, illustrated with data from microbiology. Also included are testing problemsinvolving bioequivalence, for example that a new drug is as effective as an old one. This, being aclaim by a drug company or a microbiologist, is treated as the alternative and the null hypothesisis its negation. The discussion of this difficult problem as well as its one sided versions is alsoboth simple and illuminating.

Each problem and the suggested inference procedure are introduced with a brief but cleardiscussion. This is followed by an algorithmic description of the inference procedure. Thestrength of the book lies in its simple but clear presentation, its examples from microbiology,and the insight of the author gained from working with scientists. For example, if a pilotexperiment for determining the optimal sample size leads to an unacceptably large sample size,Paulson advises the scientist to redo the pilot experiment much more carefully. Most likely, thepilot experiment was unreliable.

Readership: Statisticians working or wishing to work on statistical problems in the areaof neuroscience, using fMRI data on the brain. Also suitable for cognitive psychologistsand neuroscientists and other readers familiar with graduate level statistics. This is the firstcomprehensive book dealing with statistical analysis of fMRI image data on the brain.

This excellent interdisciplinary text begins with the basic physics behind neuroimaging throughmagnetic resonance (Chapter 1) and then goes on to discuss the technology involved in collectingthe image data (Chapter 2). The images that we see are obtained by inverse Fourier transforms onraw data. The complex procedure for generating data makes it necessary to preprocess it beforestatistical analysis can begin (Chapter 3). A statistician who wishes to participate in designingan experiment, not just analyze the data, needs to know some of these basic facts.

It appears that experiments are basically of two kinds. One may observe a subject or subjectsbefore and after a stimulus is given, and try to identify which areas of the brain are activated.Alternatively, one may try to estimate the response function of the brain to an event like flashinga checkerboard. Chapters 4 through 11 deal with basic issues as well as standard methodslike linear models, spatiotemporal models, wavelets, Bayesian methods, and multiple testing,including the topological and geometric methods of Keith Worsley, whose tragic death cut shorta brilliant career.

The final chapter discusses data from an interesting experiment on eye motion, which isrelevant in the study of schizophrenia, brain lesions, etc., which seem to lead to loss of inhibitionor poor control of unusual eye movements.

Encyclopedia of Quantitative Risk Analysis and AssessmentEdward L. Melnick, Brian S. Everitt (Editors-in-Chief)Wiley, 2008, 4 vols., 2176 pages, £ 725.00 / € 978.80 / US$ 1450.00, hardcoverISBN: 978-0-470-03549-8

Readership: Anyone who needs an authoritative explanation of aspects of risk.

Risk is defined in different ways by different people. To some it means the probability of anadverse event. To others the expected cost of such an event. But however it is defined, risk isuniversal. An encyclopedia of risk must therefore cover material ranging from technical toolsfor risk management and modelling, to material describing risk in different domains, and thisbreadth means that almost certainly some topics will have been omitted.

In view of this, it might also be regarded as unfair to pick particular topics which have beenomitted or skipped over – simply on the grounds that in such a broad area there will alwaysbe such topics. Having said that, I have a particular interest in risk modelling in the personalbanking sector, and was disappointed by the limited coverage of risk in this area – especiallysince it is so topical at present. At first I thought there was nothing on the topic at all, butthen I found one article on retail credit scoring, under the far-from-obvious heading of Risk incredit granting and lending decisions: credit scoring. Perhaps the editors could include furtherdiscussion of this area in a future edition.

My nit-picking aside, it is clear that the editors of this four volume work have made a valianteffort to cover as much as possible, and have produced a valuable reference work. It is also clear

that a massive amount of effort went into it – in addition to the two editors-in-chief, it is theproduct of the work of eleven section editors and nearly 360 authors. The publishers, too, are tobe commended: it is a rather beautiful work.

Parentage testing Appendix A: The standard normal distribution5. Testing for kinship Appendix B: Upper 1% and 5% points of χ 2 distributions6. Interpreting mixtures

Readership: Statisticians and others who wish to learn the principles of DNA matching; advancedstudents, researchers.

This is a volume in the Wiley Statistics in Practice series. It aims to introduce the key ideas ofprobability and statistics which are necessary for the evaluation of DNA evidence.

No background is assumed in probability or statistics – an introductory chapter covers these –although if this was one’s first exposure to such ideas I think the rest of the book would be hardgoing. This chapter begins by introducing the basic laws of probability, and works up throughrelevant statistical distributions to likelihood ratios, estimation, and testing, all in 18 pages. Thisis followed by another introductory chapter on population genetic models, which allow oneto determine the probability of observing given profiles in a specified population. Subsequentchapters focus on the three main applications of DNA profiling: identity testing, determinationof parentage and kinship, and interpretation of mixed DNA stains.

Computer programs are available on an associated website, and the text is illustrated using thissoftware, including screenshots from it, where appropriate. Mathematical proofs are includedwhere necessary, but these are relegated to appendices at the end of chapters, so as not to disruptthe flow of the substantive ideas. Collections of problems are given at the end of each chapter,and solutions are given at the end of the book.

Approaching this from the perspective of a statistician who would like to learn more aboutDNA profiling, I would have appreciated more detail about the background technology: the threeparagraph description in Chapter 1 proved inadequate for me to understand the basic principles,and I had to resort to the web for a more detailed explanation. Having said that, once I had foundsuch an explanation, the remainder of the book was very clear. Overall, it provides an excellentintroduction to the statistics of DNA matching. I would certainly recommend it to anyone who

Readership: People wanting to apply exponential smoothing methods in their own area ofinterest, as well as for researchers wanting to take the ideas in new directions.

This book seeks to provide a comprehensive discussion of exponential smoothing forecastingmethods from the innovations state-space perspective. The authors integrate the state-spaceapproach to exponential smoothing forecasting into a coherent whole – and have done anexcellent job. This is certainly a book I would recommend to anyone who wishes to obtain asound grasp of the area, or to a PhD student about to begin research in the area.

Exponential forecasting is an intuitively attractive and very widely used approach, with along history. The state space framework is natural structure for developing prediction intervals,maximum likelihood estimates, and procedures for model selection. The description here isaccessible, and at mathematical level which is just right to explain the ideas and methods froma practical perspective, without labouring mathematical niceties.

I particularly appreciated the format of the outline of the book in the preface, which attemptsto cater for a wide readership, and which spells out clearly what parts could be read ‘if youonly want a snack’, or for ‘readers wanting a more substantial meal’, or those who ‘want thefull banquet’. Three concluding chapters then provide ‘after-dinner cocktails’ of applications toinventory control, economics, and finance. Each chapter concludes with exercises

There is an associated website containing data sets, computer code, and additional exercises.Details of public domain R software for the methods described in the book are given.

Table of contents

Readership: Practicing statisticians.

Given a set of regions of a parameter space, observed confidence levels tell us how confident canwe be that the parameter lies in each of the regions. For example, the book’s opening illustrationdescribes how a hypothesis of bioequivalence of treatments can be examined by estimating theobserved confidence that the parameter lies in a specified interval about the value correspondingto no clinically important difference between treatments.

The basic theory of the single parameter case and the multi-parameter case are described inseparate chapters, because of the significant extra complications in the latter. Later chaptersthen look at the special cases of linear models and nonparametric smoothing methods. Thebook shows how the ideas are related to other statistical concepts, including hypothesis testing,multiple comparisons, attained confidence levels, and Bayesian approaches. It includes manyexamples, from a wide range of different application domains, based on real data. There areexercises at the end of each chapter, apart from the first, and the R code the author used isavailable from his website.

Techniques such as this touch on areas which have stimulated considerable discussion, evencontroversy, in the past. The author says ‘I am willing to let the examples presented in this bookstand on their own and let the readers decide for themselves what their final opinion is of thesemethods.’ The breadth of real examples that the author provides certainly demonstrates that thisis a class of techniques worth considering.

1. Getting started 5. Simulation2. Introduction to the R language 6. Computational linear algebra3. Programming statistical graphics 7. Numerical optimization4. Programming with R Appendix: Review of random variables and distributions

Readership: Everyone interested in learning statistical programming.

Programming skills are becoming increasingly important in the repertoire of a statistician.For example, in order to apply new methods not yet available in standard software or forsimulation studies. This book is a solid introduction to (statistical) programming and providesthe reader with all programming tools needed to approach typical problems. The programminglanguage the authors suggest for this purpose is R and they assume no prior knowledge of it.The second chapter hence is a general introduction to R which is, however, still worthwhilereading for readers already familiar with R because, for example, the chapter also explainswhat floating point numbers are. The title of the third chapter is a bit misleading because itactually does not teach how to program code that produces graphs but shows how to make use ofinbuilt R functions to obtain graphs. The actual material about programming is contained in thechapters 4–7. Many important and relevant concepts of statistical programming as, for instance,flow control, random number generation, numerical algebra, and optimization are explainedthere. Especially in chapter 4 the authors use interesting problems to illustrate the conceptsin question, but in the subsequent chapters such a motivation is often missing. In my opinionespecially the chapters 6 and 7 might gain a lot by putting the concepts discussed there moreinto a statistical framework and applying them to concrete statistical problems.

Overall, the book is a concise and easy to read introduction to programming in R; however,if used in a course on statistical programming maybe the connection of some of the concepts tostatistical problems might need some more elaboration.

Readership: Researchers who need to develop inferential tools for relatively complicatedmathematical or statistical modeling problems, statisticians and biostatisticians, advancedstudents.

The main focus of this book is to introduce empirical processes and semiparametric inferencemethods to researchers interested in developing inferential tools for relatively complicatedmathematical or statistical modeling problems. The material is mainly self-contained. Thereforethose with moderate knowledge of probability and mathematical statistics may becomeacquainted with the areas with the aid of the book. The material is divided into three parts.The first part consists of an overview of the topics avoiding basic mathematical definitions andproofs, which are introduced in later parts. The second part introduces foundations of empiricalprocesses and the third part introduces foundations of semiparametric inference. Each part isfollowed by a set of case studies of statistical or biostatistical modeling. The material is structuredin sensible way supporting the learning and understanding of useful and challenging techniquesof empirical processes and semiparametric inference. The book could well be very helpful forthose studying and applying these techniques.

The book contains a fairly comprehensive introduction of basic statistical concepts and methodsused in medical and health sciences. The basic idea is to give clear verbal explanations with goodexamples avoiding heavy mathematical definitions or formulations. My opinion is that the authorhas succeeded very well in this challenging task. By the aid of the book it should be relativelyeasy to get the main ideas, and if deeper understanding is needed a list of further references isprovided to each topic. As a marginal weak point I can mention that a very commonly adoptedfree statistical software package R is not mentioned on the list of general purpose statisticalsoftware. However, I can easily recommend this book for persons working on the area of medicalbiostatistics.

Readership: This book is suitable for those with a basic knowledge of biostatistics and statisticalmodeling. The intended audience includes epidemiologists and applied biostatisticians lookingfor a practical guide to developing and testing clinical prediction models, or health careprofessionals and health policy makers interested in critically appraising a clinical predictionmodel.

Clinical Prediction Models is an excellent practical guide for developing, assessing and updatingclinical models both for disease prognosis and diagnosis. The book’s clinical focus in this eraof evidence-based medicine is refreshing and serves as a much-needed addition to statisticalmodelling of clinical data. The book assumes a basic familiarity with modelling using generalizedlinear models, focussing instead on the real challenges facing applied biostatisticians andepidemiologists wanting to create useful models: dealing with a plethora of model choices,small sample sizes, many candidate predictors and missing data. This is an example-based bookilluminating the vagaries of clinical data and offering sound practical advice on data exploration,model selection and data presentation. Model selection is at the core of the text with in-depthdiscussion of choices of candidate predictors, pre-specified models, models with interactions,stepwise selection methods in linear models, as well as modelling using generalized additivemodels (GAM), fractional polynomials and restricted cubic splines. There are also a few pagesdevoted to more modern selection methods such as Bayesian model averaging (BMA). Thereis an excellent discussion of estimation bias, over-fitting and optimism in prediction modelsmotivating the use of methods to correct for overestimation of model coefficients. Uniformshrinkage methods, penalized maximum likelihood methods, and least absolute shrinkage andselection operator (LASSO) shrinkage for selection are discussed in some detail.

The author considers many interesting examples of clinical data throughout the text, usingdata from rich data sources like the GUSTO-1 and the SMART studies. These data sets are made

The author uses simple simulations using a few reproducible R commands to motivate the useof imputation methods and shrinkage. These simple but illuminating illustrations are one of thehighlights of the book and serve as excellent pedagogical tools for motivating good statisticalthinking.

There is some mention of statistical software available to try out the newer estimation methods.The author shows partiality to R software and provides some R code in the book and makesfull programs available of the website. This may be an impediment to some readers wedded tomenu-driven packages.

322 SHORT BOOK REVIEWS

Readership: Experimenters and statisticians involved with classic plot experiments and theiranalyses.

The 1984 first edition had 473 pages (32 chapters) compared with the second edition’s 674 (30),and many of the chapter headings and many segments of text are the same or similar in botheditions. This might give a first impression that the new revision is perhaps not worth investingin. However the exact opposite is true! New to the second edition are “modern suggestionsfor multiple comparisons . . . additional examples of split plot and repeated measures designs. . . and the use of SAS-GLM, . . . , SAS-MIXED and JMP” in various analyses. Every chapterhas been systematically re-written for greater clarity, and added explanatory material has beeninserted throughout. Many new diagrams and redrawn diagrams have been provided; those thatshow how to lay out the experimental designs are just superb and extraordinarily clear. Thereference list has increased from 44 to 99. This revision is highly recommended to those whoplan and analyze experiments of the type described.

Readership: Students and teachers of introductory statistics; statisticians wishing to communi-cate statistical theory unambiguously.

This book with its royal purple cover is dedicated (p. v) to “three groups of individuals: thosewho have overcome one or more of their statistical misconceptions, those who will . . . followin the footsteps of the first group, and those whose life’s work includes helping others to castaside false beliefs about statistics.” Those who have overcome statistical misconceptions shouldbe pleased to see the road they travelled laid out in clear terms. Those who will have to facethese misconceptions in the future should also find this book enlightening. I think the last groupare most strongly advised to buy this book, as it will encourage them to think about what theysay in their classes. Those who rely on a firm rule-based approach to statistics will be the mostdisappointed, as most of the rules they have developed will be overturned.

SHORT BOOK REVIEWS 323

The book is very highly structured, which some readers may find helpful and others mayfind irritating after a while. Each chapter consists of three to six misconceptions. For eachmisconception, there are five parts. Firstly, the misconception is stated in one or two sentences.Then, evidence is given that the misconception exists. This is in the form of quotes from journals,textbooks and websites. All the references are given in an appendix: I hope you do not find yourown work referred to there!

The third part is a section explaining why the misconception is dangerous. These sections areshort yet they manage to explain the dangers in an accessible manner to someone who has studiedan introductory statistics course. Next, the misconception is undone. Sometimes this involvesa graph or picture, sometimes it is simply a page or two of text describing helping readersto confront and then dispel the misconception. Finally, an internet assignment is given. Thisinvariably points to the book’s website, http://www.psypress.com/statistical-misconceptions/.These worked easily when I tested a handful of them, and some connected to applets producedby well-known statistics educators such as Alan Rossman and Beth Chance. Some sections alsoinclude a list of recommended reading.

Now for some details of the misconceptions themselves. Some of them are indeed dangerousmisunderstandings of statistical theory, such as “If the 95% confidence intervals that’sconstructed for one sample partially overlaps the 95% confidence interval that’s constructedfor a second sample, the two samples are not significantly different from each other at α =0.05.”

Some of them are statistical paradoxes that have been widely written about e.g. the birthdayproblem and the Monty Hall problem.

But some of them are not so much misconceptions as simplifications that many educatorswould use to introduce a topic in an unequivocal manner, so as to leave exceptions and specialcases for later study. For instance, “The null hypothesis is always a statement of ‘no difference’”would frequently be used by educators to introduce hypothesis testing. Or, “there are threedifferent measures of central tendency: the mean, the median and the mode”. Of course thereare others, but these three cover a wide variety of situations, and even three may be more thanis needed for an introductory statistics course.

This book has the potential to shake statisticians out of any complacency they have aboutconveying the precise meaning of fundamental statistical theory and methods. Since the aim ofstatistics is to be accurate and precise, this book could usefully find a place on the shelves ofmost statisticians.

Lawson begins by building a solid Bayesian background in Chapters 2, 3, and 4, coveringboth basic theory and methods, computation, and residuals and measures of goodness of fit,including AIC, BIC, and DIC. Only the treatment of priors is not as strong as that of the otheraspects of Bayesian analysis. For example the inverse gamma with very small hyperparametersis mentioned following Gelman (Bayesian Analysis, 2006), but it is not pointed out that Gelmanis actually very negative about this particular prior and mentions it as an example of priorsnot to choose for the standard deviation of random effects. He recommends the uniform,

which appears later in this book, and the half Cauchy, a relatively new prior introduced byGelman.

The remaining seven chapters provide a thorough review of modeling relative risk, and itsanalysis and mapping, different types of clustering in spatial (or spatiotemporal) distribution ofdisease, multiple (spatial) scale analysis of disease distribution, and spatiotemporal modeling.Other important topics include establishing relations between geo-referenced data and predictorslike poverty, exposure to hazardous material, etc. Also included are multivariate disease analysisand spatial survival analysis.

Lawson provides well written reviews of many topics and many aspects of those topics arecovered in his reviews. The literature cited is huge and diverse, showing the current importanceof the subjects covered. One can also gain hands training in analysis and visual presentations, sostressed in the book, by following carefully the detailed introduction to R and WinBUGS givenin the book.

Many important data sets used in the book are available at http://www.musc.edu/biometry/people/lawsonab/Data%20and%20Programs.html but do not seem to be available at the sitegiven on p. 5 of the book.

Readers of this book might also consider reading the monograph by Banerjee, Carlin, andGelfand (Hierarchical Modeling and Analysis for Spatial Data, 2004), also published byChapman and Hall. This could be a good companion volume stressing more basic theoryand also models based on Gaussian processes and variograms.

SHORT BOOK REVIEWS 327

Readership: Statisticians in pharmaceutical companies and FDA, biostatisticians interested inBioequivalence, Bioavailability and how to test these, and FDA regulations and guidelinesrelating to these very important topics.

Most statisticians, including the present reviewer, are aware that the null and alternativehypotheses for testing Bioequivalence are the opposite of the usual null and alternative fortests of superiority of a new drug over the old drug in the market. Of course the same statisticalphilosophy underlies both cases for superiority tests, the claim for the new drug is the alternative,to be established by producing enough evidence, while its negation is the null and represents asort of status quo that we abandon only when enough evidence is produced.

In the same vein, the claim that a new generic drug is Bioequivalent to the old drug, whosepatent is running out, is the alternative and its negation, namely, that they are different is thenull, representing status quo. This makes the problem very intriguing since we rarely have to testsuch nulls. In this context, it is interesting that Lehmann, in his famous book, Testing StatisticalHypotheses, published in 1959, showed that its usual formulation

H0: absolute value of deviation of population means is ≥ δ

vs

H1: the above absolute value is < δ

has an UMP Test (for given δ > 0 and some level of significance α). Lehmann’s solution camemany years before testing Bioequivalence became a hot problem.

Little do we know that the problem of Bioequivalence is far more complex and remains one ofthe most challenging problems where consensus doesn’t exist on many aspects of what should betested and how. For example, Bioequivalence of population averages or at the level of individualpatients (so switching is possible)? Moreover, there are ethical questions as to whether the testshould be made on patients or healthy volunteers available, since there is no question of the newdrug being superior. At best it can be equivalent. If the test is to be made on healthy volunteers,it can’t be a clinical trial that tests the effects of the drugs. Rather testing on volunteers canonly help decide whether the two drugs have the same sort of pharmaco-kinetic parameters, forexample whether the drugs are available at the site where a drug is needed, the period it’s there,its strength, etc. In other words that would be testing Bioavailability, rather than Bioequivalence,though clearly both are closely related.

Of over seven hundred pages, the book provides an encyclopedic coverage of all these issuesand more. It is divided up into five parts; each part is further subdivided into chapters. Part 1explains what Bioequivalence means, the history of the evolution of this concept as well asthat of Bioavailability, the pharmaco-kinetic parameters that are used to measure it. Part 1 alsodiscusses some basic designs and inference on population averages. Part 2 provides a detaileddiscussion of inference on comparing Bioavailability at the level of population averages. Thereis also a detailed discussion of FDA regulations. These two parts could lead to a good course onBioequivalence and its proxy, namely, Bioavailability.

The remaining chapters are more specialized. Part III deals with tests at the level of individuals,but these individuals are still healthy volunteers and the tests are on Bioavailability. FDArecognizes the importance of such tests but they are still unregulated. Part V provides a reviewof many other related topics, like testing of inhalers, which leave no trace on blood and so requirea different definition of Bioavailability, its measurement and test.

The reviewer notes that after FDA approval, generic drugs usually replace the original, moreexpensive drug. Such data could lead to post approval studies on Bioequivalence directly, withouttaking resort to proxies. Probably such studies are already taking place. If not, the data mentioned
