WebJan 6, 2024 · Hausman-Test: In simple termns, the Hausman-Test is a test of endogeneity. By running the Hausman-Test, the null hypothesis is that the covariance between IV(s) and alpha is zero. If this is the case, then RE is preferred over FE. If the null hypothesis is not true, we must go with the FE-model. WebHausman tests (Hausman 1978) are tests for econometric model misspecification based on a comparison of two different estimators of the model parameters.
