Dear all,
When estimating a Hausman test between fixed and random effects models for a
subsample, I got a negative chi2 value (!) together with the following
message:
model fitted on these data fails to meet the asymptotic assumptions of the
Hausman test; see suest for a generalized test
but I could not implement suest for panel. Does anyone have a hint on how to
do this?
Thanks!
Andrea
