Dear Chris,

I have similar problem. I wonder why the reviewer was not happy with the
significance of rho (i'm sure you did report it). Any comment on that?

A reviewer has asked me to perform some "model adequacy" tests of my Heckman
selecton model, i.e. a probit and a OLS regression conditional on "answering
yes" in the probit.

I interpret this as he or she wants som measures of "model fit" (other than
the standard output) and possibly some measures that have to do with
diagnostic tests and/or specification tests?

The -findit- command did not help me here, so therefore: Any help to carry
out some of these tasks is appreciated.
