Regression interaction term

WebA regression model contains interaction effects if the response function is not additive and cannot be written as a sum of functions of the predictor variables. That is, a regression model contains interaction effects if: μ Y ≠ f 1 ( x 1) + f 1 ( x 1) + ⋯ + f p − 1 ( x p − 1) For our example concerning treatment for depression, the ...
