'''CHAID''' is a type of [[decision tree]] technique. It was published in [[1980]] by Gordon V. Kass. It can be used for prediction (like [[regression analysis]]) or for detection of interaction between variables. CHAID stands for '''CH'''i-squared '''A'''utomatic '''I'''nteraction '''D'''etector.

In practice, it is often used in the context of [[direct marketing]] to select groups of consumers and predict how their responses to some variables affect other variables.
