Hi, I've generated a cox model, but I'm struggling to work out how to output predctions based on the model I've made. my.model<-coxph(Surv(duration,status) ~ gender + var1 + var2, data=mydata) My test data set looks something like this: id,actualduration,gender,var1,var2 a,65,m,1,3 b,34,f,1,5 ... What i need to do is for each id, output a predicted duration based on my cox model so that I can compare it with other models. I've looked in the survival package, and the Design package, but I can only see how to output survival probabilities. I'm probably missing something obvious, but trawling the mail archives has been fruitless, any suggestions? Cheers, George
