Description: An implementation in base 'R' of the CHAID (Chi-squared
    Automatic Interaction Detection) decision tree algorithm of Kass (1980)
    <doi:10.2307/2986296> and the Exhaustive CHAID variant of Biggs, de Ville,
    and Suen (1991) <doi: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.
