Miscellaneous functions for classification and visualization, e.g.
regularized discriminant analysis, sknn() kernel-density naive Bayes, an

supervised classification, partimat() visualization of classification rules

categorical data, corclust() variable clustering, variable extraction from
different variable clustering models and weight of evidence
