Fixed effects Another way to see the fixed effects model is by using binary variables. So the equation for the fixed effects model becomes: Y it = β 0 + β 1X 1,it +…+ β kX k,it + γ 2E 2 +…+ γ nE n + u it [eq.2] Where –Y it is the dependent variable (DV) where i = entity and t = time. –X k,it represents independent variables (IV), –β
