WebInterpret Interactions in Linear Regression. For a linear regression model with interaction: Y = β0 + β1 X1 + β2 X2 + β3 X1X2. The coefficient of the interaction term (β3) is the … We may use two techniques to decide whether to include the interaction term in the model. Initially, a scatterplot can help us identify whether the linear relationship between a continuous predictor (bgpa) and a continuous outcome (mgpa) varies depending on a categorical predictor (gre).
