What is optimal binning in SPSS?

The Optimal Binning procedure discretizes one or more scale variables (referred to henceforth as binning input variables) by distributing the values of each variable into bins. Bin formation is optimal with respect to a categorical guide variable that “supervises” the binning process.

When should you use binning?

Feature Binning: Binning or discretization is used for the transformation of a continuous or numerical variable into a categorical feature.
