Hello everyone
I've a problem while comparing the results of two regressions.
These two Regs are performed with different datasets and I want to compare
the adj-R2 (coefficients are not my concerns)
I know Vuong test can help to compare R2 if using the same dataset.
But since I use different dataset but the same regression model, I wonder
if any proc in SAS can test whether an adj-R2 is significantly different
from another one.

Many thanks.

Will
