　　After a brief review of elementary statistical theory， the coverage of thesubject matter begins with a detailed treatment of parametric statisticalmodels as motivated by DeFinetti's representation theorem for exchangeablerandom variables （Chapter l）. In addition， Dirichlet processes and othertailfree processes are presented as examples of infinite-dimensional param-eters. Chapter 2 introduces sufficient statistics from both Bayesian andnon-Bayesian viewpoints. Exponential families are discussed here becauseof the important role sufficiency plays in these models. Also， the conceptof iriformation is introduced together with its relationship to sufficiency.A representation theorem is given for general distributions based on suffi-cient statistics. Decision theory is the subject of Chapter 3， which includesdiscussions of admissibility and minimaxity. Section 3.3 presents an ax-iomatic derivation of Bayesian decision theory， including the use of condi-tional probability. Chapter 4 covers hypothesis testing， including unbiasedtests， P-values， and Bayes factors. We highlight the contrasts between thetraditional "uniformly most powerful" （UMP） approach to testing and de-cision theoretic approaches （both Bayesian and classical）. In particular， wesee how the asymmetric treatment of hypotheses and alternatives in theUMP approach accounts for much of the difference. Point and set estima-tion are the topics of Chapter 5. This includes unbiased and maximum like-lihood estimation as well as confidence， prediction， and tolerance sets. Wealso introduce robust estimation and the bootstrap. Equivariant decisionrules are covered in Chapter 6. In Section 6.2.2， we debunk the commonmisconception of equivariant rules as means for preserving decisions un-der changes of measurement scale. Large sample theory is the subject ofChapter 7. This includes asymptotic properties of sample quantiles， maxi-mum likelihood estimators， robust estimators， and posterior distributions.The last two chapters cover situations in which the random variables are
　　not modeled as being exchangeable. Hierarchical models （Chapter 8） areuseful for data arrays. Here， the parameters of the model can be modeled as exchangeable while the observables are only partially exchangeable. We introduce the popular computational tool known as Markov chain MonteOarlo， Gibbs sampling， or successive substitution sampling， which is very useful for fitting hierarchical models. Some topics in sequential analysis are presented in Chapter 9. These include classical tests， Bayesian decisions， confidence sets， and the issue of sampling to a foregone conclusion.
