Hello everyone! My question:

I have a base-regression of: Comp_i= ₀+₁female+₂treatment+₃female*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 (=which can take the value (as in 1st 2nd 3rd or 4th place) 1,2,3 or 4), Beliefs (= can take the value (as in: I think I was the 1st 2nd 3rd or 4th place)1,2,3 or 4) and risk (= can take the values 0 or 1 (as in I take risk or not)).

Q: How would the model look? How would the interaction coeff look like? <<<

Thanks for any help! I really appriciate it!
