The Method Tab

You can use the Method tab (Figure 29.3) to set options in the analysis. The tab supports the following options:

Number of canonical variables

specifies the number of canonical variables. This option corresponds to the NCAN= option in the PROC DISCRIM statement.

Covariance within groups

specifies assumptions about the homogeneity of within-group covariances. This option corresponds to the POOL= option in the PROC DISCRIM statement.

Prior probability of group membership

specifies assumptions about the prior probabilities of group membership. This option corresponds to choosing either the EQUAL or PROPORTIONAL option in the PRIORS statement.

Classify observations by

specifies a method of classifying observations based on their canonical scores. This option corresponds to the CROSSVALIDATE option in the PROC DISCRIM statement.
