st: SVYHECKMAN

[Ayse Akincigil <aakincigil@ihhcpar-mail.rutgers.edu>]

Has anyone experimented with the new survey versions of heckman and
heckprob? 

I can not estimate the standard errors with SVYHECKMAN.

When I ran Heckman ignoring the survey design, stata does provide the
estimates for standard errors. However, in the first few iterations, the log
likelihood is not concave.

Thank you
