How do you find coefficient of determination
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: WebJan 21, 2024 · The coefficient of determination, often denoted R 2, is the proportion of variance in the response variable that can be explained by the predictor variables in a regression model. This calculator finds the coefficient of determination for a given regression model.
