WebAn R 2 of 1.0 indicates that the data perfectly fit the linear model. Any R 2 value less than 1.0 indicates that at least some variability in the data cannot be accounted for by the model … The coefficient of determination (R²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable. The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R² will be to … See more You can choose between two formulas to calculate the coefficient of determination (R²) of a simple linear regression.
