Hello everyone! My question:

I have a base-regression of: Comp_i= ₀+₁female+₂treatment+₃feamle*treatment

Where: female = 0,1; treatment = 0,1,2; Comp_i= 0,1

Explanation:

I have an experiment where men and women have to make indivdual decisions (they do it (=1) or they dont do it (=0); = Comp_i). Men (= 0) and women (= 1) are split equally into 3 different treatments (0 (=controlgroup), 1 and 2). I want to see if the decisions that the men and women have to make is influenced by the treatment.

--> Now i want to add three more independent variables to the regression, because I think they might have an influence. Performance (=1,2,3,4), Beliefs (=1,2,3,4) and risk (=0,1). How would the model look? How would the interaction coeff look like?

Thanks for any help!
