Canonical Variates Analysis

Select menu: Stats | Multivariate Analysis | Canonical Variates

Canonical variates analysis operates on a within-group sums of squares and products matrix, calculated from a set of variates and factor that specifies the grouping of units. It finds linear combinations of the variates that maximize the ratio of between-group to within-group variation, thereby giving functions that can be used to discriminate between the groups.
