Resampling scheme based on the total dataset and iterative multi-splitting scheme based on a 5-fold cross validation. Apart the performance metric (mean AUC in that case) it is of equal importance to report the standard deviation across the folds to get an indication of robustness of the model. Low standard deviations are reflecting stable and robust models that are not influenced by the specific test set
