The Automatic Interaction Detector (AID) is discussed as to its usefulness in multiple regression analysis. The algorithm of AID-4 is a reversal of the model building process; it starts with the ultimate restricted model, namely, the whole group as a unit. By a unique splitting process maximizing the between sum of squares for the categories of…

The use of interaction and non-linear terms in multiple regression poses problems for determining parsimonious models. Several computer programs for using these terms are discussed. (JKS)

Many proposed moderators, "explanatory variables," in personnel psychology are probably illusory, having been created solely by belief in the law of small numbers. Race is one such illusory moderator. Also described is a model for validity generalization that questions the traditional doctrine of situational specificity of test…
