On: Why I’m Not a Fan of R-Squared

[otl1248]

Maybe the fact that this is in the (reasonably brief) Wikipedia entry on R2 is some evidence?

https://en.wikipedia.org/wiki/Coefficient_of_determination#I...

Also, I find that the OP is actually more confusing on this topic than Wikipedia.

Not sure how else I can support that this is a basic fact about this metric. I'm not in the mood to find quotes in intro textbooks, etc.
