In this second edition of a reference/text, Baker (educational psychology, emeritus, University of Wisconsin-Madison) and Kim (educational psychology, University of Georgia) provide three new chapters on parameter estimation with multiple groups, parameter estimation for a test with mixed item types, and Markov chain Monte Carlo methods. Appendices illustrate the implementation of each estimation procedure, and examples drawn from various research studies demonstrate concepts and relationships discussed in the text. A companion CD-ROM, also new to this edition, contains BASIC and Java codes for estimation algorithms discussed in the book. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
