Hi all,

my question is just one.
Do I need to center categorical dummy variable when modeling interaction
terms, like gender variable in the example below? What is the main
difference of centering categorical variable or not? In my case, if I center
Gender my coefficient reported is negative, on the other hand, if I not
center Gender, the report coefficient is positive. So, which is the best?


Ex. Revenues + MeanCenterRevenues*Gender
