WebThe equation for this model without interaction is shown below: E ( Y) = β 0 + β 1 x 1 + β 2 x 2. The term we add to this model to account for, and test for interaction is the product of x 1 and x 2 as follows: E ( Y) = β 0 + β 1 x 1 + β 2 x 2 + β 3 x 1 x 2 To see why this works, consider the following factorisations of this regression ...
