  "Description": "An implementation of CHAID, a type of decision tree\ntechnique for a nominal scaled dependent variable published in\n1980 by Gordon V. Kass. CHAID stands for Chi-Squared Automatic\nInteraction Detection and detects interactions between\ncategorized variables of a data set, one of which is the\ndependent variable. The remaining variables may or may not be\nordered. An algorithm for recursive partitioning is\nimplemented, based on maximizing the significance of a\nchi-squared statistic for cross-tabulations between the\ndependent variable and the predictors at each partition. The\ndata are partitioned into mutually exclusive, exhaustive\nsubsets that best describe the dependent variable. Multiway\nsplits are used by default.",
