Roc receiver operating curve
Web25 Jul 2024 · Receiver operating characteristic curve (ROC curve) In point form: The ROC curve is a plot of sensitivity vs. false positive rate (1-specificity) Sensitivity is on the y-axis, from 0% to 100% The ROC is for tests which produce results on a numerical scale, rather than binary (positive vs. negative results) WebThe ROC curve is used to assess the overall diagnostic performance of a test and to compare the performance of two or more diagnostic tests. It is also used to select an optimal cut-off value for determining the presence or absence of a disease.
