If you are modelling a categorical variable, then you need to declare
that in the model.
For example, if -var- is categorical, then you would enter it into a
regression as -i.var- and place -xi:- in front of the regression
command.
See -help xi-.

please see my other response for a proper rephrasing of the question.
