The Receiver Operating Characteristic (ROC) curve is a useful tool to measure the classification capability of continuous variable assess accuracy medical test that distinguishes between two conditions. Sometimes, covariates related diagnostic may increase discriminating power ROC curve. Due lack stability classical curves estimators outliers, we introduce procedure obtain robust in presence co...

Lampinen (2016) suggested that proponents of ROC analysis may prefer that approach to the diagnosticity ratio because they are under the impression that it provides a theoretical measure of underlying discriminability (d'). In truth, we and others prefer ROC analysis for applied purposes because it provides an atheoretical measure of empirical discriminability (namely, partial areaunder-the-cur...

Which eyewitness identification procedure better enables eyewitnesses to discriminate between innocent and guilty suspects? In other words, which procedure better enables eyewitnesses to sort innocent and guilty suspects into their correct categories? The answer to that objective, theory-free question is what policymakers need to know, and it is precisely the information that ROC analysis provi...
