I ran a few MLE regressions and set them up first as pooled data and second
as panel data. The regression coefficients were almost identical, only a
variation of a few decimal points, and the standard errors were much lower
in the panel regression. I was expecting the coefficients to still be an
unbiased estimate in both regressions, but I expected that they should be
slightly different from each other. Is this unusual?
