The problem with -margins- is likely to be that you are asking a question that it cannot answer.
So, people who know about this kind of thing will want to see what you typed before as your -stcox- command.

I'm trying to run the following command after the Cox Regression:
. margins, at(max_red=20) atmeans predict(basesurv)
I'm getting the following error note:
prediction is a function of possibly stochastic quantities other than e(b)
r(498);
On the other hand, when I'm running:
predict a1,basesurv
(8405 missing values generated)
The command works fine.
My question is what is the problem with the command "margins"?
