Thank you in advance,

I have a question regarding the mlogit command for multinomial logistic regression.

say I run a command:

mlogit rep78 mpg make


Then I use the command listcoef


When I compare the beta coefficients from listcoef for each of the comparisons, they do not match the coefficients from the mlogit command!

If I change the base outcome to the right value, then the coefficients match.  Otherwise, it does not match.

I do not understand.  I also went through the examples provided by Freese et al. and I see that the coefficients from listcoef are supposed to match the corresponding comparisons from mlogit.

Any theories why?  Thank you.
