In addition to the excellent responses given, with which I concur, you
could treat the variable as multinomial, regress it onto your
independent variables by fitting -mlogit-, and then test the IIA
assumption with the user-written -mlogtest- (downloadable via STB:
-net stb 58 sg155-). If the IIA is violated, then you might consider
combining a couple of the indicators of your response variable before
running it through -ologit- or -oprobit-. Then again, you might think
of all this as rather too exotic.

I didn't realize that -mlogtest- was originally an STB program. I don't know if it has changed much over the years, but the most current version is contained in -spost9-, available on Scott Long's web site. ( -findit spost9- ). The spost9 suite has a lot of other useful programs, including -brant-, which tests whether the assumptions of the ordered logit model are violated.
