The new STATS NTILE ANALYSIS extension procedure is now available on the Extension Hub. This procedure, also known in the literature as decile analysis, groups the predicted probabilities from a classification procedure such as logistic regression, trees, and SVM (another extension command) in order to better understand their distribution and to assist in formulating decision rules.  The output includes a table of statistics for the ntiles of the probabilities and, optionally, several charts to help to understand the distribution.
