See the Section on 404 errors after clicking a link in WordPress. So it generates the panel variable as 2727 years and it won't separately stop generating quarters every time it's a new state. FE remove the effect of those time-invariant characteristics so we can assess the net effect of the predictors on the outcome variable. Each entity is different therefore the entitys error term and the constant (which captures individual characteristics) should not be correlated with the others. regressione dati panel r - blogas.hobi.lt Cambridge University Press.
