Fig. 2From: The Matthews correlation coefficient (MCC) should replace the ROC AUC as the standard metric for assessing binary classificationSolution of Eq. 9 for AUC \(={\pi }/{4} \simeq 0.785\). The points within the yellow area are all the possible (TNR, TPR) points when the ROC AUC has value 0.785. Please notice that the ROC curve with \(AUC = 0.785\) is not represented here. The black-dotted curve depicted here is one of the boundaries of the yellow areaBack to article page
