Re: st: Test of ordered probit vs ordinary probits

Hi everybody. I have a question about ordered probits that follows
on from the FAQ by Bill Gould about the role of the constant/cutoffs:
The assumptions of the ordered logit model can be tested via the
-brant- command, which is part of the -spost9- package of Long and Freese.
Ordered logit and ordered probit assumptions can be tested via Wolfe
& Gould's -omodel- command.
Assumptions of ologit & oprobit can also be tested via my -gologit2-
command. Further, gologit2 provides a means of selectively relaxing
constraints on individual variables when assumptions are violated
while maintaining them when not violated. More on gologit2 at
http://www.nd.edu/~rwilliam/gologit2/index.html
Everything except -spost9- is available from SSC. -spost9- is
maintained directly by Long. All of this can be found with -findit-.
