I know the components of R2 as in ESS, TSS, RSS.
I know cov(x,y) = [[itex]\sum[/itex](yi - ybar)(xi - xbar)]/n-1
But that's as far as I can go, I have come across lowercase r yet or the sample correlation and proofing how they all fit is a bit beyond me so if someone can provide some help that would be great thanks.
This is not homework.
