# IntcensROC (R package) - same AUC regardless of input parameters

I have a data frame including various continuous variables (size of a lymph node measured in different ways) and an outcome (disease-free interval).

I have used the intcensROC package to assess the suitability of the size of the lymph node as a marker of disease-free interval with interval censored data.

U <- ASAC_tot$Left # left side of the interval censor data V <- ASAC_tot$Right # right side of the interval censor data
Marker <- ASAC_tot$lymph.node.size # lymph node size Delta <- ASAC_tot$CENSOR_DFI # censuring status
pTime <- 180 # to determine to predicted time
res <- intcensROC (U, V, Marker,  Delta, pTime, gridNumber = 500)
