Re: st: slogit versus mlogit

Hi
I wonder if anyone can help me?
I am trying to model an ordinal response variable with three levels.
I do not have proportional odds and so I have been investigating the
stereotype model. I understand that if the stereotype model is of
its maximum dimension, in my case 2, then the model is equivalent
to a multinomial logistic regression model. Given that I believe
that a 2-dimensional model would be an improvement over a
1-dimensional model for my data, is there any benefit in fitting the
model using slogit rather than mlogit? Alternatively, does anyone
know where I can find detailed information on the interpretation of
a 2-dimensional stereotype type model from slogit, especially when
my explanatory variables are categorical?
Thanks

(Self-plug here) You may also want to take a look at -gologit2-.
-gologit2- provides a means for estimating models that are less
restrictive than ologit and more parsimonious than mlogit. The
program can be downloaded from SSC. The support page for -gologit2-,
which includes a pre-publication version of an article that is in the
current Stata journal, can be found at
