Fast Interaction at Mac App Store analyse

Fast Interaction conducts regression analyses to determine if two continuous variables interact to predict a criterion variable. Fast Interaction automatically mean centers the predictor variables and creates the corresponding product term predictors. Results are presented in a table and a 2-D/3-D graph. Simple-slope lines are calculated and displayed in the context of the 3-D surface. Fast Interaction does not support interactions between categorical variables or between categorical and continuous variables.
