Fig. 1From: The Matthews correlation coefficient (MCC) should replace the ROC AUC as the standard metric for assessing binary classificationROC curves passing through the point X. Among all ROC curves passing through the point \(X(\text {tnr},\text {tpr})\) (with x coordinate expressed in terms of the secondary TPR axis), the black one is the curve maximising the AUC area, marked in yellow. The red dotted curve and the blue dotted curve represent two random ROC curves that pass through the highlighted X black pointBack to article page
