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. Nick n.j.cox@durham.ac.uk Yuval Arbel 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"? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
