Hi Gurus:
 
In the coxph() objects in Survival package, there is an attribute called residuals. Usually, there are several kinds for censored survival data. I can't seem to find in the documentation as to which one this is calculating. Anyone knows?

Hi Karen,

those are martingale residuals.

You don't have to be a Guru to find it out.
Did you check
?coxph
Under values it tells you
"an object of class "coxph". See coxph.object for details."
So you can ask for help for coxph.object
?coxph.object

and then you will see among the components:
residuals
the martingale residuals.

I hope this helps,
Roland
