This is done automatically when you have two categorical variables and two continuous variables. This is equivalent to asking whether the two slopes differ across the two categorical variables.

Hi all,
I was wondering how I could test for interaction effects between a categorical variable and a continuous variable using QDEC. Is there a way to do so?
Thank you.
