CHi-squared Automatic Interaction Detector(CHAID) algorithm model is applied in social surveys and market segmentation. It is mainly used to classify cohorts by determining the characteristics of several predictors based on a dependent variables. This review article introduces the core concepts,operational precede,and development of the CHAID algorithm model. Compared with Logit model,this article also discusses the advantages,disadvantages,and restrictions of CHAID model. Furthermore,this article points out some questions for further research for the model.
