Hi all.
When calculating a model with "ologit" (same bug? with "oprobit" or "regress" for that matter) with many independent categorical variables (25 in all; model has >2500 observations) and then using "predict yhat, xb" I get a bunch of cases (not all) with predictions=0; when calculating the linear predictor by hand, the results are perfectly identical to the stata output of the other non-zero predictions and the cases where stata predicted a 0, all calculate to non-zero numbers. Any ideas?
Regards!
