Overview for Discriminant Analysis

Use Discriminant Analysis to classify observations into two or more groups when you have a sample with known groups.

Using this analysis, you can do the following:
  • Determine how accurately the observations are classified into the known groups
  • Evaluate how the predictor variables differentiate the groups
  • Predict the groups for observations that have unknown groups

For example, a high school administrator uses discriminant analysis to determine which of three educational tracks a student should be placed in.
