Automatic Interaction Detection (AID)

AID (Automatic Interaction Detection) is a classification program developed by Morgan & Sonquist (1963) that led to the development of the THAID (Morgan & Messenger, 1973) and CHAID (Kass, 1980) classification tree programs. These programs perform multi-level splits when computing classification trees. For discussion of the differences of these programs from the algorithms used in the Classification Trees module, see the Comparisons with Other Classification Tree Programs section of the Classification Trees Overviews.
