- but how close is "very close"? I don't think it can be,
with 30/31 as the R-squared expected by chance.
Using the adjusted R-squared formula in Cohen and Cohen,
the distance from 1.0 will be 30 times as big as the observed,
so that .9954 will be shrunk to .86. Assuming that you do start
with the full number of variables in the equation, as is usually
recommended. But you still get "a lot" of shrinkage by my
book, even if you say the error is (say) only 10 times as
big as the observed error of 0.0046.
