WebDec 21, 2024 · Many textbooks point out that the R-square statistic in multivariable regression has a geometric interpretation: It is the squared correlation between the response vector and the projection of that vector onto the linear subspace of the explanatory variables (which is the predicted response vector). WebDec 1, 2016 · R squared between two vectors is just the square of their correlation. So you can define you function as: rsq <- function (x, y) cor (x, y) ^ 2 Sandipan's answer will return you exactly the same result (see the following proof), but as it stands it appears more readable (due to the evident $r.squared ). Let's do the statistics
