Dear all,

It is so weird,  I'm working on oprobit model using Stata 11.
The problem arrive when I try to compute predicted probabilities
against the variables of the model. I never got this error before, any
suggestion?


 di norm(_b[_cut1]-_b[Gender]*1)
unknown function norm()
r(133);


 di norm(_b[/cut1]-_b[Gender]*1)
unknown function norm()
r(133);
