provides a bucket (equal-length) binning method
-
provides a Winsorized binning method and Winsorized statistics
-
provides a quantile binning method and a pseudo–quantile binning method
-
provides a mapping table for the selected binning method
-
provides a basic statistical table that contains the minimum, maximum, mean, median, and so on
-
computes the quantiles of the binning variables
-
calculates the weight of evidence (WOE) and information value (IV) based on binning results
-
reads input data in parallel and writes output data in parallel when the data source is in a database on the appliance
