I am struggling with the interpretation of the coefficients within interaction models.
I am looking at the outcome of an interaction model of 2 binary (dummy variables). I was just wondering how I interpret the: - Intercept (is everything at 0)? - The slope coefficients? - The interaction coefficients?
In standard multiple linear regression, we talk about the change in y when we have a 1-unit change in x, holding everything else constnat. How do we interpret this in interactions? Especially since both my variables are dummy?
Hope this makes sense and thanks very much in advance.
