Description Usage Arguments Value Author(s) References See Also

This function provides an analysis of the effect of each model term by comparing the binary classification performance between the Full model and the model without each term.
The model is fitted using the train data set, but probabilities are predicted for the train and test data sets.
Reclassification improvement is evaluated using the `improveProb`

function (`Hmisc`

package).
Additionally, the integrated discrimination improvement (IDI) and the net reclassification improvement (NRI) of each model term are reported.
