In a Regression model, should you drop interaction terms if they’re not significant? In an ANOVA, adding interaction terms still leaves the main effects as main effects. That is, as long as the data are balanced, the main effects and the interactions are independent. The main effect is st...

Under the logistic regression framework, we propose a forward-backward method, SODA, for variable selection with both main and quadratic interaction terms. In the forward stage, SODA adds in predictors that have significant overall effects, whereas in the backward stage SODA removes unimportant terms...
Let’s perform our analysis. All statistical software allow you to add interaction terms in a model. Download the CSV data file to try it yourself:Interactions_Categorical. Use the p-value for an interaction term to test its significance. In the output below, the circled p-value tells us ...
Empirical Examples Comparing the Differences in Simple Slopes and the Interaction Term Example 1. The first example was taken from Robinson and Schumacker (2009). This study examined the effects of centering on multicollinearity for interaction terms in regression m s (Equation 1) with a continuous...
We provide practical advice for applied economists regarding robust specification and interpretation of linear regression models with interaction terms. We replicate a number of prominently published results using interaction effects and examine if they are robust to reasonable specification permutations. ...
