Subject: ROC
My question would be related more to time-dependent ROC (survivalROC package):
I would like to know how true positives (TP) and false positives (FP) are related to the order of survival times and diagnostic markers. That is, having the a set of TP and FP, each of them is calculated from which diagnostic marker and survival times. Let's take mayo data set. How could I match the TP and FP generated from survivalROC function to cut.values (output) and Stimes (input)?
Best,
Carol
