I believe you can use the "cluster' and "robust" options for standard errors
with -heckman- and -heckprob-, if that's what you mean.

Subject: st: Selection with panel data
I was wondering if anyone had written any code to estimate a selection
model in STATA with panel data. I think that Limdep have developed
something that they are planning on including in release 8.0 of Limdep, so
I thought maybe STATA might have done something similar.
