Hello Statalist,

I have used a heckman twostep selection process. After employing the
test I get 2 tables, the selection and the regression table. What
puzzles me, that in the one of the tables STATA gives me the
coefficient but does not report a standard error, confidence intervall
and the z value for a dummy but does so in the other regression table.

I could not figure out what the problem might be, does anybody know
any help? Also does that mean that I cannot interpret the
coefficients?

Thank you for your help

With kind regards,

Georg Wernicke
