WebConversely, if the distance is small, the null is not rejected, and random effects is preferred because it is more efficient. Since you have a large test statistic, the distance is large, and you should reject the null and use fixed effects. However, there is an additional complication. In theory, the matrix V_b - V_B should be positive definite.

The considerably weaker exogeneity assumption of FE models compared to that of OLS models implies that the former cannot estimate the coefficients of time-constant covariates at the same observation level as the fixed effects, which is an important drawback of FE models.
