This example runs without a hitch for me:
*************
clear*
cmp setup
webuse laborsup
gen byte kids2 = kids + int(uniform()*3)
cmp (kids=fem_educ) (kids2=fem_educ), ind($cmp_oprobit $cmp_oprobit) nolr
tech(dfp) qui
*************
You may want to -ssc uninstall cmp- and then -ssc inst cmp-.
What does -which cmp- give you?

Betreff: Re: st: RE: Heckman two-step estimator
Thank you Martin. I ran a bivariate seeming unrelated ordered probit
just to understand the command. It says ghk2setup() not found.
However, ghk2 is already installed and the software is up-to-date. I
am using stata11. I also ran an example given in the help. It says the
same. Searched web to learn more about ghk2setup() but no clue as to
what is happening.
Any thoughts?
Thanks,
Sridhar
