WebArea under the curve = Probability that Event produces a higher probability than Non-Event. AUC=P (Event>=Non-Event) AUC = U 1 / (n 1 * n 2 ) Here U 1 = R 1 - (n 1 * (n 1 + 1) / 2) where U1 is the Mann Whitney U statistic and R1 is the sum of the ranks of predicted probability of actual event. It is calculated by ranking predicted probabilities ...

WebApr 17, 2024 · A density of a continuous random variable is (traditionally) always normalised such that the integral over the density (i.e. area under curve) equals to one. Density plots in R will be normalised such the area under curve equals to one. There exist some nice posts here on SO that explicitly demonstrate that point; see e.g. here and here. WebAug 9, 2024 · Suppose we calculate the AUC for each model as follows: Model A: AUC = 0.923. Model B: AUC = 0.794. Model C: AUC = 0.588. Model A has the highest AUC, which indicates that it has the highest area under the curve and is the best model at correctly classifying observations into categories.
