The Cox model (stcox) which also build upon the same assumption have a post estimation command (estat phtest) which is easy to use, but this option is missing in stcrreg.  I have a dataset with approx. 300 000 individuals and 5 covariates which I want to include in the competing risk regression.  Other statausers that have used stcrreg, how did you check  for this?  Any suggestions?
