Non-parametric ROC summary statistics

Pardo, M.C.; Franco Pereira, Alba
Abstract:
Receiver operating characteristic (ROC) curves are useful statistical tools for medi- cal diagnostic testing. It has been proved its capability to assess diagnostic marker’s ability to distinguish between healthy and diseased subjects and to compare differ- ent diagnostic markers. In this paper we introduce non parametric ROC summary statistics to assess a ROC curve across the entire range of FPFs ∈ (0, 1) as well as over a restricted range of FPFs and compare them with some existing ones through a simulation study and through some real data examples. We also show their capability to compare two diagnostic markers.
