Interactions Among Group Regressions: An Old Method in a New Setting.
Aiken, Lewis R., Jr.
The purpose of the Neyman-Johnson statistical technique is to determine a region or span of values on r independent variables where the predicted criterion scores of two or more treatment groups are significantly different. Consequently, the technique should prove especially useful in research concerned with moderator variables or with the interactions between treatments and person variables. The mechanics of the technique are reviewed and some extensions mentioned. Three simple examples are given. (Author)
