Dear All
I am currently running dprobit with many dummy variables as well as some
continuous variables (i.e. age etc). When I run the regression, some of
the z-values are missing although standard errors are estimated.

Could you please let me know when STATA compute standard errors but not
z-values?
Thank you very much for your help.
Best Wishes,
Asako
