WebMay 10, 2014 · Nonetheless, I decided to test the robustness of my model against one with (country) fixed effects. Now, at least in Stata, the Hausman test doesn't work with robust standard errors. Since it looks at the coefficients, not the standard deviation, though, I can use the FE with uncorrected standard errors without problems for the Hausman test.
