R-squared

R-squared, a measure found on Morningstar. com, shows strength of correlations between funds and benchmark indexes, but not directions of movement.

Kind of like simply choosing the regression with the highest R-squared.

I was a perfectionist at the bench and a part of me is concerned terrified that my slaves trainees/staff may not be as careful and will produce questionable data but watching my summer student admonish herself for having a standard curve with an R-squared of 0.9998 instead of 1.0 has allayed those fears somewhat!

When randomizing the phosphorylation sites within each phosphoprotein, keeping the number of phosphorylation sites in each specific phosphoproteins constant the average R-squared is higher than the observed with the experimentally determined phosphorylation sites pink curve.

But it's not really right to conclude in this case that personality explains almost nothing about ideology just because the R-squared is small.

Since national average IQ correlates so strongly with ease of doing business R-squared=46%, it looks like L/V's two main factors are, to some extent, just one big factor: IQ.

And even with that, you can achieve high R-squared correlations.

Actually, both measures are likely to be very imprecise, which could result in a small R-squared even if the actual relationship is very strong.
