st: Calculating Mills Ratio After biprobit

[Sachin Chintawar <schint1@tigers.lsu.edu>]

Dear Statausers
I was wondering if we had a command like HECKPROB (for probit) for
calculating Mills ratio after biprobit. If we do not can anyone tell
me how we can do this manually in Stata While the same can be done in
R (refer: http://cran.r-project.org/web/packages/sampleSelection/sampleSelection.pdf
- pg 9) and LIMDEP (Manual), is there a simpler way?
Thanks
Sachin
