For example, with 353 districts, there would be a considerable loss of degrees of freedom by invoking fixed effects. In addition, random effects allows one to obtain estimates taking account of permanent cross-section or between variation.

When physicians were investigating whether maternal smoking leads to poor birth outcomes, they determined that evidence from traditional longitudinal studies was unreliable because smokers and non-smokers are behaviourally different in so many ways aside from smoking status.

estimator for the coefficients on time invariant variables in a fixed effects model is also untrue. That part of the parameter vector remains unidentified. The “estimator” relies upon turning the fixed effects model into a random effects model, in which case simple GLS estimation of all (now identified) parameters would be efficient among all Provided the fixed effects regression assumptions stated in Key Concept 10.3 hold, the sampling distribution of the OLS estimator in the fixed effects regression model is normal in large samples. The variance of the estimates can be estimated and we can compute standard errors, \(t\)-statistics and confidence intervals for coefficients.

The “estimator” relies upon turning the fixed effects model into a random effects model, in which case simple GLS estimation of all (now identified) parameters would be efficient Controlling for variables that are constant across entities but vary over time can be done by including time fixed effects.
