- type: doi
  value: 10.32614/CRAN.package.chaidr
abstract: An implementation of the CHAID (Chi-squared Automatic Interaction Detection)
  decision tree algorithm of Kass (1980) <https://doi.org/10.2307/2986296> and the
  Exhaustive CHAID variant of Biggs, de Ville, and Suen (1991) <https://doi.org/10.1080/02664769100000005>,
  as specified in the 'IBM SPSS' Statistics Algorithms documentation. Supports nominal,
  ordinal (with floating missing category), and continuous predictors, and nominal,
  ordinal, and continuous response variables using Pearson chi-squared, Goodman row-effects,
  and one-way ANOVA F tests respectively. Includes prediction, rule extraction, gains
  and lift analysis, validation on holdout data, and visualization via base graphics,
  'Graphviz' DOT, 'plotly', and conversion to 'partykit' objects.
