Hey-
I've been trying to run an mprobit model in Stata, and I'm having all
sorts of trouble specifying my constraints.  They work fine with mlogit,
but for some reason won't function for mprobit.  Here's an example of
what's happening:
. constraint 1 [1]ref_Chances=0

. mprobit vote_choice ref_Chances cons_Chances lib_Chances ndp_Chances,
constraints(1)
Constraints invalid:
equation [1] not found


Has this happened to anyone else?  Any insights?
