Hi all,
I'm really hoping that someone can help me with this!
I am running logistic regression models. In the models, I included two independent variables: 1 is a dummy variable that accounts for a complete partisan alternation in government; and the other is a continuous variables that captures the ideological differences between two governments.
Now I wanted to include an interaction term with these two variables, as I want to know the specific impact of government alternation and a change in government ideological profiles.
The problem is
1. Is this feasible? Is it possible to run an interaction term with a dichotomous and a continuous variable?
2. I do not know how to interpret the regression coefficients signs. A negative sign indicates the effect of inexistent partisan alternation in government or does it indicate the effect of small ideological differences between governments?
Can anyone help me with this?
Thank you!
