Hi, thank you all for those who helped me on prediction of newdata for linear model,
 it is my new question on the prediction of coxph for newdata, for example,

i have the model:

coxout<-coxph( Surv(time, status) ~ x

predict(coxout) will give the fitted values

I have tried predict(coxout, newdata), it still gave me the fitted values only.

Can anyone hlep me on how to do prediction for coxph? thank you very much!
