I am trying to estimate  a Cox model with Conditional Frailty (as in  Box-Steffensmeier et al. 2007) along with stratification. There is a error message in stata that say that"option strata(varname) not allowed for shared frailty models". The stratification variable and id variable are different in my model. Did you resolve your problem. I have read you question in FAQ in Stata. Could you help me?
Best wishes
