WebThis section focuses on the entity fixed effects model and presents model assumptions that need to hold in order for OLS to produce unbiased estimates that are normally distributed in large samples. These assumptions are an extension of the assumptions made for the multiple regression model (see Key Concept 6.4) and are given in Key Concept 10.3. WebA fixed effects regression consists in subtracting the time mean from each variable in the model and then estimating the resulting transformed model by Ordinary Least Squares. This procedure, known as “ within ” transformation, allows one to drop the unobserved component and consistently estimate β.

"WebSomething similar is tested when you apply the LM-test by Breusch and Pagan after the random effects regression where the null hypothesis is that $\text{Var}(u_i) = 0$. In your case, a significant F-test means that the fixed effects are non-zero and therefore pooled OLS and random effects will be biased if $\text{Cov}(X_{it},u_i)\neq 0$.
