Hi list,
I was trying to use "predict.coxph" to calculate martingale
residuals on a test
data, however, as pointed out before
What about resid(fit) ? It's my reading of Therneau & Gramsch [and of
help(coxph.object) ] that they consider those martingale residuals.

predict(mycox1, newdata, type="expected") is not implemented yet.

suggested to use 'cph' and 'predict.Design', but from my reading so
far, I'm not
sure they can do that.
Do you other ways to calculate martingale residuals on a new data?
Thank you very much!
