It is based on tion to probability and mathematical statistics and it is intended for students.

A year of calculus, including Taylor Series and multivariable calculus, and an introductory course in linear algebra are prerequisites. Such a course should include some traditional topics in mathematical statistics such as methods based on likelihood , topics in descriptive statistics and data analysis with special attention to graphical displays, aspects of experimental design, and realistic applications of some complexity. These themes, properly interwoven, can give students a view of the nature of modern statistics. Furthermore, many students take only one course in statistics and do not have time for two or more. Analysis of Data and the Practice of Statistics In order to draw the above themes together, I have endeavored to write a book closely tied to the practice of statistics. It is in the analysis of real data that one sees the roles played by both formal theory and informal data analytic methods. I have organized this book around various kinds of problems that entail the use of statistical methods and have included many real examples to motivate and introduce the theory. Among xi xii Preface the advantages of such an approach are that theoretical constructs are presented in meaningful contexts, that they are gradually supplemented and reinforced, and that they are integrated with more informal methods. At the same time, I have not shied away from using the mathematics that the students are supposed to know. I moved the material from the last chapter, a point that was never reached by many instructors, and integrated it into earlier chapters.

The second chapter introduces some fundamental concepts in statistical decision theory and inference. Chapters contain detailed studies on some important topics: A large number of exercises in each chapter provide not only practice problems for students, but also many additional results.

In addition to improving the presentation, the new edition makes Chapter 1 a self-contained chapter for probability theory with emphasis in statistics. Added topics include useful moment inequalities, more discussions of moment generating and characteristic functions, conditional independence, Markov chains, martingales, Edgeworth and Cornish-Fisher expansions, and proofs to many key theorems such as the dominated convergence theorem, monotone convergence theorem, uniqueness theorem, continuity theorem, law of large numbers, and central limit theorem. A new section in Chapter 5 introduces semiparametric models, and a number of new exercises were added to each chapter. The revised and updated version remains of high quality, and I recommend it for use as a text or reference book in a graduate statistics program. The main changes include addition of new material in Chapter 1, addition and deletion of a number of exercises, addition of two new sub-sections ….

The book remains valuable to instructors and graduate students of traditional mathematical statistics courses, specially for its large collection of problems and for its rigourous presentation.

Cancel reply. Please enter your comment! Chapter 3 continues the treatment of random variables by going into joint distributions.

The instructor may wish to skip lightly over Jacobians; this can be done with little loss of continuity, since they are rarely used in the rest of the book. The material in Section 3. Expectation, variance, covariance, conditional expectation, and moment-generating functions are taken up in Chapter 4. This method is used several times in the statistics chapters.

The law of large numbers and the central limit theorem are proved in Chapter 5 under fairly strong assumptions. Chapter 6 is a compendium of the common distributions related to the normal and sampling distributions of statistics computed from the usual normal random sample. It is useful for students to have these distributions collected in one place. Chapter 7 is on survey sampling, an unconventional, but in some ways natural, beginning to the study of statistics. However, there is a certain virtue in this grubbiness, and students are given practice in such calculations. The method of moments, the method of maximum likelihood, and Bayesian inference are developed. Section 8. This subject is further developed in Chapter Informal, graphical methods are presented here as well.

Several of the last sections of this chapter can be skipped if the instructor is pressed for time. These include Section 9. A variety of descriptive methods are introduced in Chapter Many of these techniques are used in later chapters. The importance of graphical procedures is stressed, and notions of robustness are introduced. The placement of a chapter on descriptive methods this late in a book may seem strange. When I teach the course, I introduce some of this material earlier. For example, I have students make boxplots and histograms from samples drawn in labs on survey sampling.

## Mathematical Statistics - 1st Edition

If the instructor wishes, the material on survival and hazard functions can be skipped. Classical and nonparametric methods for two-sample problems are introduced in Chapter The chapter concludes with some discussion of experimental design and the interpretation of observational studies.

The instructor has much more freedom in selecting material from Chapters 12 through In particular, it is not necessary to proceed through these chapters in the order in which they are presented. Chapter 12 treats the one-way and two-way layouts via analysis of variance and nonparametric techniques.

Chapter 13 is a rather brief treatment of the analysis of categorical data. Likelihood ratio tests are developed for homogeneity and independence. Chapter 14 concerns linear least squares. I chose to employ matrix algebra but keep the level of the discussion as simple and concrete as possible, not going beyond concepts typically taught in an introductory one-quarter course.

In particular, I did not develop a geometric analysis of the general linear model or make any attempt to unify regression and analysis of variance.
