(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
