WebSpecification Test -Hausman 8 The fixed effects estimator is more accurate than the random effects estimator, but less efficient (larger variance). In turn, the random effects … WebTo decide between fixed or random effects you can run a Hausman test where the null hypothesis is that the preferred model is random effects vs. the alternative the fixed effects (see Green, 2008, chapter 9). It basically tests whether the unique errors (ui) are correlated with the regressors, the null hypothesis is they are not.

Suppose that we have two estimators for a certain parameter θof dimension K×1.One of them , bϑ r, is robust, i.e. consistent

WebFirst, the test statistic may be undefined because the estimated VCE does not satisfy the required asymptotic properties of the test. Second, the classic Hausman test applies only to the test of the equality of two estimators. Third, the test requires access to a fully efficient estimator; such an estimator may not be available, for example,
