cfitcp2 <- coxph(Surv(start,stop,status)~sex+rels+factor(treat)+log(age)+log(tcrate3+0.01)+cluster(trialno)+strata(enum),data=bdat5,model=TRUE,x=TRUE,y=TRUE)
I would now like to use the model to predict the probability of zero events by two years - this is equivalent to the survival probability at 2 ye...
