Can you give an example using datasets shipped with Stata? Otherwise it
should be a case for tech support...

Betreff: st: predict bug?
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!
