How do you find coefficient of determination
WebYou can either view it's described by the line or by the variation in x. And this number right here, this is called the coefficient of determination. It's just what statisticians have … WebIn short, the " coefficient of determination " or " r-squared value ," denoted r2, is the regression sum of squares divided by the total sum of squares. Alternatively, as demonstrated in this screencast below, since SSTO = SSR + SSE, the quantity r2 also equals one minus the ratio of the error sum of squares to the total sum of squares:
