Dear Statalisters,
This is probably a very basic question, but I couldn't find the answer (or
the correct syntax) for it.
I am trying to run an ANOVA command on my regression, to see how much of the
variation in the dependent variable do my fixed effects explain.
Any suggestions will be more than welcomed!
Thanks
Andrea
