In other presentations, the authors have provided macros that efficiently compute univariate statistics for hundreds of variables at a time. The classic example is when a modeler must fit a binary model (two-valued target) and has available hundreds of potential numeric predictors. Such situations may occur when third-party data sets are added to in-house(More)
