Multinomial Logistic Regression is NOMREG.
If I remember well, DISCRIM requires continuous and normally
distributed predictors (also, multivariate homogeneity of variances is
On the other hand, logistic regression methods can be used with
I insist you take a look at log-linear methods (GENLOG). Agresti's
book (Categorical Data Analysis. New York: Wiley. )has several
chapters about them, with worked examples. Also, you can take a look
Also, HILOGLINEAR, can be of help.
