In case of a single regressor, fitted by least squares, R 2 is the square of the Pearson product-moment correlation coefficient relating the regressor and the response variable. More generally, R 2 is the square of the correlation between the constructed predictor and the response variable.n this form R 2 is expressed as the ratio of the explained variance (variance of the model's predictions, which is SS reg / n) to the total variance (sample variance of the dependent variable, which is SS tot / n).
