WebIn both such cases, the coefficient of determination normally ranges from 0 to 1. There are cases where R2can yield negative values. This can arise when the predictions that are being compared to the corresponding outcomes have not been derived from a model-fitting procedure using those data. WebThe " coefficient of determination " or " R-squared value ," denoted R 2, is the regression sum of squares divided by the total sum of squares. Alternatively (as demonstrated in the video below), since SSTO = SSR + SSE, the quantity R 2 also equals one minus the ratio of the error sum of squares to the total sum of squares:
