Taking into account novel multivariate analyses as well as new options for many standard methods, this renamed, new edition shows readers how to perform multivariate statistical analyses and understand the results. For each of the techniques presented, the authors use the most recent software versions available, including R, and discuss the most modern ways of performing the analysis. Along with more problems and data sets, this fifth edition includes a new chapter on regression of correlated outcomes. Data sets and code are available for download online.
