ABSTRACT
Discriminant analysis is used for two purposes: (1) to describe mean differences among the groups in MANOVA; and (2) to classify participants into groups on the basis of a battery of measurements. Since this text is primarily focused on multivariate tests of group differences, more space is devoted in this chapter to what is often called descriptive discriminant analysis. We also discuss the use of discriminant analysis for classifying participants, limiting our attention to the two-group case. We show the use of SPSS for descriptive discriminant analysis and SAS for classification.
