Re: st: Mlogit with constraints

Your results look quite peculiar. You specify constraints 1-3 but
mlogit reports 9 constraints. The model has -1 degrees of

I ran a multinomial logit with constraints and after that I used the command
"predict" to get the predicted probabilities. Stata result was: same
probabilities for 3 alternatives. Do you know any other command to predict the
probabilities when mlogit with constraints is used?
I suspect something is wrong with your model specification. We need
to see more. Include the actual constraints commands you are
using. I don't think the problem is with the predict command (which
seems to be working correctly given the parameter estimates) but with
the model itself.
