WebRandom effects models •It is often useful to treat certain effects as random, as opposed to fixed –Suppose we have k effects. If we treat these as fixed, we lose k degrees of freedom –If we assume each of the k realizations are drawn from a normal with mean zero and unknown variance, only one degree of freedom lost---that Web10.4. Regression with Time Fixed Effects. Controlling for variables that are constant across entities but vary over time can be done by including time fixed effects.
