Oliver Eger <egolto15@yahoo.de> asked these questions when he finished a
thread about a another topic. For his benefit, I repost under a more
appropriate topic heading.

In Stata testing of the PH assumption is quite easy, but what makes me a
little irritated: all commands for checking the PH assumption are
related to the Cox analysis. But: If the propotional hazard assumption
is violated, the results from cox models as well as from parametric
models like Weibull have to be handled with caution, isn´t it?

Why are there no commands like "estat phtest" after stcox, to check the
PH assumption directly after a streg command?
