WebAug 23, 2024 · Second, the name itself gives the impression that some quantity \(R\) is being squared to produce a result. Either way, it seems that \(R^{2}\) should probably lie in \([0,1]\), or at the very least it should be nonnegative. The computational definition of \(R^{2}\), however, is divorced from both the notation and this common interpretation. WebThe value of R-squared represents the unexplained variation for a regression equation. FALSE In multiple regression, each individual coefficient must have an R-squared of 0.05 or greater.
