Here is what I got:
In this case, what is the next step? What to do when the proportional hazards assumption is not met?
Here is what I got:
Code:
estat phtest Test of proportional-hazards assumption Time: Time ---------------------------------------------------------------- | chi2 df Prob>chi2 ------------+--------------------------------------------------- global test | 95.70 12 0.0000 ----------------------------------------------------------------
