Hi, I am trying to carry out a Hausman test on panel data (using males and females) to clarify if I should use a fixed or random-effects model. However, when I do this I get a p-value of 1 (which I am assuming means something has gone wrong). I have tried to use "sigmamore" and "xtoverid" but neither seem to have any impact - if anyone has any ideas they would be much appreciated!
