Hi Stata Experts Team,

I would like to know whether there is a different procedure in regression if there is independent variable dummy and moderator variable dummy. The current model I used for the model is fixed effect and I have checked the normality, multicolinearity, heteroscedasticity, and also the autocolinearity. Is the any additional procedure that I should perform for the model below?

Thank you for your attention.
