Aahh, epiphany…thanks for the links Francisl…I believe lesson #60 from the Khan Academy nails it: Calculating R-Squared. Correct me if I’m wrong…The only problem is I’ve had to start at lesson one and I have quite a few more to go, but they’re jogging my memory of past studies of statistics. It’s for real world application too. Now I know to write R^2 properly!!!
