This is a complete, self-contained introduction to matrix analysis theory and practice. Matrix methods have evolved from a tool for expressing statistical problems to an indispensable part of the development, understanding, and use of various types of complex statistical analyses. This evolution has made matrix methods a vital part of statistical education. Traditionally, matrix methods are taught in courses on everything from regression analysis to stochastic processes, thus creating a fractured view of the topic. This updated second edition of "Matrix Analysis for Statistics" offers readers a unique, unified view of matrix analysis theory and methods. "Matrix Analysis for Statistics, Second Edition" provides in-depth, step-by-step coverage of the most common matrix methods now used in statistical applications, including eigenvalues and eigenvectors; the Moore-Penrose inverse; matrix differentiation; the distribution of quadratic forms; and more. The subject matter is presented in a theorem/proof format, allowing for a smooth transition from one topic to another. Proofs are easy to follow, and the author carefully justifies every step.
Accessible even for readers with a cursory background in statistics, yet rigorous enough for students in statistics, this new edition is the ideal introduction to matrix analysis theory and practice. The book features: self-contained chapters, which allow readers to select individual topics or use the reference sequentially; extensive examples and chapter-end practice exercises, many of which involve the use of matrix methods in statistical analyses; new material on elliptical distributions and new expanded coverage of such topics as eigenvalue inequalities and matrices partitioned in 2 by 2 form, in particular, results relating the rank, generalized inverse, eigenvalues of such matrices to their submatrices, and much more; and, optional sections for mathematically advanced readers.
