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.
Best Regards, Heidi Foo
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.

Dear Douglas,
Thank you for your reply. Does this mean that if I were to have a continuous variable (i.e. Neuroinflammation) and a categorical variable with 2 levels (i.e. gene positive and gene negative), interaction can also be found using QDEC?
Thank you.
Best Regards, Heidi Foo
