Understanding auc-roc curve

WebManually calculating the AUC. We can very easily calculate the area under the ROC curve, using the formula for the area of a trapezoid: height = (sens [-1]+sens [-length (sens)])/2 width = -diff (omspec) # = diff (rev (omspec)) sum (height*width) The result is 0.8931711. Web17 Jun 2024 · AUC stands for Area Under the Curve. In this case, it means the Area Under the ROC Curve (AUC-ROC). It is a metric that tells you how separable your positive and negative responses are from each other. This metric varies with the model we choose for the problem in hand.
