Good morning,
I am using a fixed effect model.
How can I express the interaction between the regressors?
I mean: bewteen my regressors there are immiration and natural growth. Natural growth (from descriptive analysis I made) has the same trend as immigration(t-1), so I suppose that immigration strongly influences natural growth. How can I express this relation?
And apart from this, any suggestion on how to analyse the residuals in a fixed effect model like xtreg y x1 x2..., fe?
Thanks a lot
Val
