WebI obtained the following output after running the Hausman test: 1) CASE 1 Hausman Test chisq = 13.943, df = 4, p-value = 0.007478 alternative hypothesis: one model is inconsistent. 2) CASE 2 Hausman Test chisq = 0.49157, df = 4, p-value = 0.9743 alternative hypothesis: one model is inconsistent WebThe Hausman test can be used to differentiate between fixed effects model and random effects model in panel analysis. In this case, Random effects (RE) is preferred under the null hypothesis due to higher efficiency, while under the alternative Fixed effects (FE) is at least as consistent and thus preferred. eighth\\u0027s 0u

WebUnder the null, both the sigma from the RE estimation and the sigma from the FE estimation are consistent. The formula for the vcv uses sigma. For example, in a RE estimation you automatically use the RE sigma in the vcv. But there is nothing stopping you from replacing it with the FE sigma and getting a slightly different, but also consistent ... WebChoosing between FE and RE Hausman test – Measure of the difference between the FE estimate and the RE estimate – H 0: coefficients estimated by the RE estimator are the same as the ones estimated by the FE estimator – Rejection of null hypothesis: the two models are different, and reject the random effects model in favor of fixed effects WebAug 24, 2024 · The Hausman test showed a 5% level of significance chi (5) = 13.493, p = 0.019 < 0.05, implying that the FE model was superior compared to the RE model.
