Chi-square automatic interaction detection (CHAID) [1] is a decision tree technique based on adjusted significance testing (Bonferroni correction, Holm-Bonferroni testing). [2][3]

CHAID analysis splits the target into parent nodes, then uses statistical algorithms to create child nodes. Unlike regression, CHAID does not require normally distributed data.

Jul 11, 2023 · CHAID is a predictive model used to forecast scenarios and draw conclusions, involving regression, machine learning, and decision trees. It analyzes the data to apply chi …

Feb 26, 2024 · This article explores the implementation of the CHAID algorithm in decision trees. We’ll first learn about decision trees and the chi-quare test, followed by the practical …

Jul 23, 2025 · CHAID (Chi-squared Automatic Interaction Detector) is a decision tree technique used for segmenting datasets by identifying significant interactions between categorical variables.

CHAID, or Chi-squared Automatic Interaction Detection, is a classification method for building decision trees by using chi-square statistics to identify optimal splits.

One such method is CHAID. Decision trees partition the data set into mutually exclusive and exhaustive subsets, which results in the splitting of the original data resembling a tree-like …
