WebSep 13, 2024 · The AUC* or concordance statistic c is the most commonly used measure for diagnostic accuracy of quantitative tests. It is a discrimination measure which tells us how well we can classify patients in two groups: those with and those without the outcome of interest. Since the measure is based on ranks, it is not sensitive to systematic errors in ... WebAug 18, 2024 · ROC Curve and AUC. An ROC curve measures the performance of a classification model by plotting the rate of true positives against false positives. ROC is short for receiver operating characteristic. AUC, short for area under the ROC curve, is the probability that a classifier will rank a randomly chosen positive instance higher than a …
