Receiver operating characteristic (ROC) curves have seen increasing use to assess the accuracy of diagnostic tests that yield continuous test results. We can calculate a fully non-parametric ROC curve from the empirical false positive rate (FPR) and true positive rate (TPR) at each possible decision threshold, but it may be quite jagged. We can obtain a smooth ROC curve by directly fitting a parameteric model, for example, binormal or bilogistic, to the actual test results, but substantial lack… CONTINUE READING
