Are there any utilities/packages for showing various performance metrics of a regression model on some labeled test data? Basic stuff I can easily write like RMSE, R-squared, etc., but maybe with some extra utilities for visualization, or reporting the distribution of prediction confidence/variance, or other things I haven't thought of. This is usually reported in most training utilities (like caret's train), but only over the training data (AFAICT). Thanks in advance.
