Betreff: st: Anciliary parameters not found - oprobit

Dear all,
I am facing the following problem and don't know how to get the
anciliary parameters:


. oprobit EDUC AGEY AGEY2 SEX NONCONGO

Iteration 0:   log likelihood = -1122.1342
Iteration 1:   log likelihood = -1046.0122
Iteration 2:   log likelihood = -1045.7553
Iteration 3:   log likelihood = -1045.7552

Ordered probit regression                         Number of obs   =
954
                                                  LR chi2(4)      =
152.76
                                                  Prob > chi2     =
0.0000
Log likelihood = -1045.7552                       Pseudo R2       =
0.0681
