Substitute x = G ( q) in the above equation and get. μ n ′ = ∫ 0 1 G n ( q) d q. which may be easier to compute numerically. Note that q = F ( x) so that d q = f ( x) d x. Central moments are computed similarly μ = μ 1 ′. WebFeb 8, 2024 · To get a ROC curve you basically plot the true positive rate (TPR) against the false positive rate (FPR). To indicate the performance of your model you calculate the area under the ROC curve (AUC). Lets say we trained a XGBoost classifiers in a 100 x 5-folds cross validation and got 500 results. horizon tech coils
