What Does It Mean If The Interaction Effect Is Not Significant In Process Macro Moderation Interactions in Multiple Regression The interaction term between the two regressors X_1 and X_2 is given by their product X_1 times X_2. . And because hierarchy allows multiple terms to enter the model at any step it is possible to identify an important square or interaction term even if the associated linear term is not strongly related to the response. Earlier we fit a linear model for the Impurity data with only three continuous predictors. Interaction effect means that two or more featuresvariables combined have a significantly larger effect on a feature as compared to the sum of the individual variables alone. Your new feature space becomes x1x2x3x1x2x1x3x2x3 You can fit your regression model on top of that. An interac...
