WebROC curves are typically used with cross-validation to assess the performance of the model on validation or test data . ROC curves calculated with the perfcurve function for (from left … Web1 day ago · Here, let’s compare two different performance metrics: accuracy and ROC-AUC. Accuracy: the proportion of the data that are predicted correctly. ROC-AUC: a metric that computes the area under the ROC curve (which compares specificity and sensitivity). A higher value of ROC-AUC indicates better performance.
