Software tools for roc and auc estimates
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. WebThe area under an ROC curve (AUC) is a popular measure of the accuracy of a diagnostic test. In general higher AUC values indicate better test performance. The possible values …
