Adjusted/Within/Between R squared

[Darcy Hill]

Hi,

I would be very grateful if someone could confirm whether my understanding is correct.
I ran a panel regression, then asked stata for the adjusted r squared, can I assume this is the within r squared? My panels are local authorities.

"The adjusted r squared is 0.361 for dry recycling and 0.699 for compost, telling us only 36.1% of the variation in dry recycling rates is explained by the independent variables, and 69.9% of the variation in compost recycling rates."

Is it the variation in dry recycling rates, or the variation within local authorities in dry recycling rates?

Thank you in advance!
Darcy

The regular output of -xtreg- does not include an "adjusted r squared." I presume you looked at the value of e(r2_a). Yes e(r2_a) is an adjusted r squared calculated from the within r squared. In your proposed statement, I would replace "% of variation" by "% of within-authority variation" throughout.

Thanks Clyde this is very helpful!
