Multinomial Logistic Discriminant Analysis is estimated in Q when the Dependent question is a Pick One question with Variable Type of Categorical and contains three or more categories.

Multinomial Logistic Discriminant Analysis is more commonly referred to as Multonimial Logit (MNL), however, this is a different type of MNL model to the one most commonly used in the analysis of Experiments, which is why it is referred to as Multinomial Logistic Discriminant Analysis in Q.

Coefficients and related statistics

With Multinomial Logistic Discriminant Analysis, there are separate coefficients corresponding to all but the first category of the dependent question. Note that the Value Labels of the categories of the dependent question are in the first column:
