Thanks Nick and Richard (your example works fine), I did not know that
predict was specific to the previous estimation command. There's
something new to learn about stata every day...
Therefore the question is resolved.
Well then the problem clearly is that in the do-file that I was given,
there is no nlogitrum at all, which is strange because why would there
be that specific predict for nlogitrum then...
best, stefan bernhard,
