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

This means the p-value indicates that there is short evidence against the null hypothesis being invalid. WebIn statistics, a fixed effects model is a statistical model in which the model parameters are fixed or non-random quantities. This is in contrast to random effects models and mixed models in which all or some of the model parameters are random variables.
