基本説明
This classic textbook introduces multivariate analysis to nonstatisticians in the biomedical, social, and management sciences. Each chapter in this fifth edition features an updated discussion and listing of computer software packages, including S-PLUS, SAS, SPSS, Stata, and STATISTICA.
Full Description
This new version of the bestselling Computer-Aided Multivariate Analysis has been appropriately renamed to better characterize the nature of the book. Taking into account novel multivariate analyses as well as new options for many standard methods, Practical Multivariate Analysis, Fifth Edition shows readers how to perform multivariate statistical analyses and understand the results. For each of the techniques presented in this edition, the authors use the most recent software versions available and discuss the most modern ways of performing the analysis.New to the Fifth EditionChapter on regression of correlated outcomes resulting from clustered or longitudinal samplesReorganization of the chapter on data analysis preparation to reflect current software packagesUse of R statistical softwareUpdated and reorganized references and summary tablesAdditional end-of-chapter problems and data setsThe first part of the book provides examples of studies requiring multivariate analysis techniques; discusses characterizing data for analysis, computer programs, data entry, data management, data clean-up, missing values, and transformations; and presents a rough guide to assist in choosing the appropriate multivariate analysis. The second part examines outliers and diagnostics in simple linear regression and looks at how multiple linear regression is employed in practice and as a foundation for understanding a variety of concepts. The final part deals with the core of multivariate analysis, covering canonical correlation, discriminant, logistic regression, survival, principal components, factor, cluster, and log-linear analyses.While the text focuses on the use of R, S-PLUS, SAS, SPSS, Stata, and STATISTICA, other software packages can also be used since the output of most standard statistical programs is explained. Data sets and code are available for download from the book's web page and CRC Press Online.
