Resilience Family of Receiver Operating Characteristic Curves

A new semiparameteric model of the receiver operating characteristic (ROC) curve based on resilience family or proportional reversed hazard is proposed, which an alternative to existing models. The resulting ROC and its summary indices (such as area under Youden index) have simple analytic forms. partial likelihood method applied estimate curve. Moreover, estimation methodologies been developed estimators exploiting Mann–Whitney statistics Rojo approach. simulation study has carried out assess performance all considered estimators. Real data from American National Health Nutrition Examination Survey analyzed in detail proposed usual binormal prevalent literature. context brain injury-related biomarkers are also order compare our with Lehmann curves. Finally, we show that may be applicable misspecification scenario through Ducheme muscular dystrophy data.
