Hyojoung,
If -findit probit heteroskdasticity- doesn't turn up any canned programs
for testing, you'll have to do it by hand. A test for heteroskedasticity
in probit models is described in Davidson and MacKinnon's 1993 book, pp.
526-527. It doesn't look too hard to implement.
An alternative is to assume you have heteroskedasticity and use -hetprob-.
I have nothing to suggest about ordered probits, I'm afraid.
Cheers,
Mark
