Question for standard deviation in split validation

LouisWu

When using split validation for training and testing, how to make the Rapidminer display the standard deviation for auc, sensitivity, and recall et al. ? (now only mean value was displayed)

If you are conducting a split validation, there is no standard deviation to display for performance metrics, because you have only a single model validation. If you want to see the standard deviation, you need to use one of the cross-validation methods, so it has multiple validation performances to compare.
