WebThe Hausman test is the standard procedure used in empirical panel data analysis in order to discriminate between the fixed effects and random effects model. 1 The general set up can be described as follows. Suppose that we have two estimators for a certain parameter θof dimension K×1.One of them , bϑ r, is robust, i.e. consistent WebThe Hausman test The Hausman test statistic The Hausman test statistic is defined as m = q′(var ^FE var ^RE) 1q; with q = ^FE ^RE. Under RE, the matrix difference in brackets is positive, as the RE estimator is efficient and any other estimator has a larger variance. The statistic m is distributed ˜2 under the null of RE, with degrees
