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. Steve On Dec 20, 2012, at 3:46 PM, Oliver Eger wrote: 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? * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
