WebbThere are several definitions of R2that are only sometimes equivalent. One class of such cases includes that of simple linear regressionwhere r2is used instead of R2. When only an interceptis included, then r2is simply the square of the sample correlation coefficient(i.e., r) between the observed outcomes and the observed predictor values.[4] WebbThe ratio of the variance or predicted to the variance of dependent variable is called R 2, and it's between 0 and 1 in OLS. It happens so that when you have only one independent variable R 2 = R, the Pearson correlation coefficient.
