abstract: An implementation of CHAID, a type of decision tree technique for a nominal
  scaled dependent variable published in 1980 by Gordon V. Kass. CHAID stands for
  Chi-Squared Automatic Interaction Detection and detects interactions between categorized
  variables of a data set, one of which is the dependent variable. The remaining variables
  may or may not be ordered. An algorithm for recursive partitioning is implemented,
  based on maximizing the significance of a chi-squared statistic for cross-tabulations
  between the dependent variable and the predictors at each partition. The data are
  partitioned into mutually exclusive, exhaustive subsets that best describe the dependent
  variable. Multiway splits are used by default.
