I can easily get the other parameter estimates by using coxph() but don't know how to get the baseline hazard estimates from it. Does anyone know how to obtain nonparametric baseline hazard estimates in the gamma frailty model? Thanks, YH
I don't see what the problem is. fit1 <- coxph(Surv(time, status) ~ age + ph.ecog + frailty(inst), data=lung) sfit <- survfit(fit1) plot(sfit) Please give an actual example of the problem.
