Subject: syvcoxph and cox.zph for testing the PH assumption
Hello, is it kosher to call cox.zph on a syvcoxph model fit? I see that
someone proposed a modified version of cox.zph that uses resid(fit,
'schoenfeld', **weighted=TRUE**).
https://stats.stackexchange.com/questions/265307/assessing-proportional-hazards-assumption-of-a-cox-model-with-caseweights
Is that all it takes?
Thanks,
Youyi
