Re: st: Multinominal Logit

["E. Paul Wileyto" <epw@mail.med.upenn.edu>]

The command mlogit is correct. Syntax is like all stata commands:

commandname yvar xvarlist, options

Yvar would be your multinomial outcome, and your xvarlist will be used 
across the model.

Pay attention to your reference group. If you do not like the one 
automatically chosen, you may set the reference group in the options.

It is also useful in mlogit to know how to use stata constraints. This 
will help you test whether effects can be modelled with a common beta 
across different parts of the model.
