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 16, 2024 · Precision-recall curve plots true positive rate (recall or sensitivity) against the positive predictive value (precision). In the middle, here below, the ROC curve with AUC. On the right, the associated precision-recall curve. Similarly to the ROC curve, when the two outcomes separate, precision-recall curves will approach the top-right corner. WebMar 3, 2024 · I can't think why anyone would care how the test performs at $\alpha \simeq 0.9$, per se.However, the ROC curve is monotonically increasing, so the power at $\alpha\simeq 0.9$ bounds the power elsewhere. In practice the bound is likely to be very weak for $\alpha \lesssim 0.1$ or so of actual interest.. Let's consider the average power …
