## About the Author

In addition to readers of the earlier editions listed in those prefaces I want to thank Michael Perlman and Kathy Richards for their assistance in getting this manuscript ready. Stanford, California February T.

This new edition purports to bring the original edition up to date by substantial revision, rewriting, and additions. The basic approach has been maintained, llamely, a mathematically rigorous development of statistical methods for observations consisting of several measurements or characteristics of each sUbject and a study of their properties.

The general outline of topics has been retained. The method of maximum likelihood has been augmented by other consid- erations. In point estimation of the mf"an vectOr and covariance matrix alternatives to the maximum likelihood estimators that are better with respect to certain loss functions, such as Stein and Bayes estimators, have been introduced. In testing hypotheses likelihood ratio tests have been supplemented by other invariant procedures. New results on distributions and asymptotic distributions are given; some significant points are tabulated.

Properties of these procedures, such as power functions, admissibility, unbi- asedness, and monotonicity of power functions, are studied. Simultaneous confidence intervals for means and covariances are developed. A chapter on factor analysis replaces the chapter sketching miscellaneous results in the first edition. Some new topics, including simultaneous equations models and linear functional relationships, are introduced. Additional problems present further results. FOr a comprehensive listing of papers until and books until the reader is referred to A Bibliography of Multivariate Statistical Analysis by Anderson, Das Gupta, and Styan Further references can be found in Multivariate Analysis: I am in debt to many students, colleagues, and friends for their suggestions and assistance; they include Yasuo Amemiya, James Berger, Byoung-Seon Choi.

Special thanks go to Johanne Thiffault and George P. H, Styan for their precise attention. Seven tables of significance points are given in Appendix B to facilitate carrying out test procedures. Tables 1, 5, and 7 are Tables 47, 50, and 53, respectively, of Biometrika Tables for Statisticians, Vol. Pearson and H. Table 2 is made up from three tables prepared by A.

Simulation and Computa- tion Tables 3 and 4 are Tables 6. Nagarscnkcr and K. Pillai, Aerospacc Research Laboratorics The author is indebted to the authors and publishers listed above for permission to reproduce these tables. California June T.

It is hoped that the book will also serve as an introduction to many topics in this area to statisticians who are not students and will be used as a reference by other statisticians. For several years the book in the form of dittoed notes has been used in a two-semester sequence of graduate courses at Columbia University; the first six chapters constituted the text for the first semester, emphasizing correla- tion theory.

It is assumed that the reader is familiar with the usual theory of univariate statistics, particularly methods based on the univariate normal distribution. A knowledge of matrix algebra is also a prerequisite; however, an appendix on this topic has been included. It is hoped that the more basic and important topics are treated here, though to some extent the coverage is a matter of taste. Some 0f the mOre recent and advanced developments are only briefly touched on in the late chapter.

The method of maximum likelihood is used to a large extent. This leads to reasonable procedures; in some cases it can be proved that they are optimal.Some aspects of statistics exploit computational power such as the resampling technologies; these are not covered here.

When the individual is drawn ran- domly, we consider the vector as a random vector with a distribution or probability law describing that population.

We think of the entire vector as an observation from a multivariate population or distribution. First consider the case of two real random variables t X and Y. We think of the entire vector as an observation from a multivariate population or distribution.
