Hello everyone! My question is about regression models:

I have an experiment where men and women have to make indivdual decisions (they do it (=1) or they dont do it (=0). 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.

Is it right that I would have to use a probit regression because my dependet variable is binary? How would the base-regression model look like?

Thanks for any help!!
