I am using the rcorr.cens function from the Hmisc package and the
time-dependent ROC curve obtained using tdrocc in the survcomp package.
I understand that the C statistic from rcorr.cens has to be subtracted from 1
if high values of the risk variable lower survival.
Given that I wonder what the connection is between that C statistic and the AUC
from the tdrocc object. If they are substantially different are there any
views on which one is to be preferred ?
Many thanks in advance
