Although I found the package pROC with he comparison of correlated ROC curves, I did not find anything about the comparison of uncorrelated ROC curves. Does anybody know how to compare the AUC of wo uncorrelated ROC curves? (Why do I want to do this? I have two samples an older and a newer one.The question is, if the diagnostic test (AUC of ROC curve) is better in either the older or newer sample or if they are equal.) Thanks for any help!
