R-Squared (R2)


  • A statistical measure indicating how good one term is at predicting another. Perfect predictions would result in R2 values of 1.0. If one term is useless for predicting the other, then R2 would be 0.0. The higher the R2, the better the prediction. More technically, R2 measures how well variability in one term predicts the variability in the other.  1
