HOW to use the survivalROC to get optimal cut-off values?
...use the time-dependent survivalROC package.according to
the,reference material,it only gives a set of ordered cut-off values
.eg.
--------------------------------------------------------------------------------
data(mayo)
str(mayo)
attach(mayo)
ROC.1=survivalROC(Stime=time,status=censor,marker=mayoscore4,predict.time=365,lambda=0.05)
str(ROC.1)
plot(ROC.1$FP, ROC.1$TP, type="l", xlim=c(0,1), ylim=c(0,1),
xlab=paste( "FP", "\n", "AUC = ",round(ROC.1$AUC,3)),
ylab="TP",main="Mayoscore 4, Method = NNE \n Year = 1") abline(0,1)...
