Correction for optimism of AUC for both core and extended models. Auc.boot is the distribution of the AUC value in the bootstrap sample, which represents “an estimation of the apparent performance.” “auc.orig” is the distribution of the AUC value deriving from the model fitted to the bootstrap samples and evaluated on the original sample, which represents the model performance on independent data. At the bottom of the chart, the apparent AUC (i.e., the value deriving from the model fitted to the original dataset) and the AUC adjusted for optimism are reported on the box plot respectively with the blue line and red line [25]
