coefficient of determination, (5) (6) Where, called Pearson's product moment correlation coefficient (PPMCC) Another way of defining (see Equation 3) is to describe it as the proportion of variation in the response data that is explained by the regression model. We note that.

Coefficient of Determination - Statistics Solutions
Sample coefficient of non-determination (k2) is the ratio of residual variation to initial variation. Sample coefficient of determination (r2) is the ratio of removed variation to initial variation. (r2 = 1 - k2). LEAST-SQUARES regression line is the line that produces the minimum residual variation. UNCERTAINTY IN REGRESSION

The coefficient of determination is a number between 0 and 1, inclusive. That is, If r2 = 0, the least squares regression line has no explanatory value. If r2 = 1, the least-squares regression line explains 100% of the variation in the response variable.
