How to Find Coefficient of Determination (R-Squared) in R

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 … See more You can choose between two formulas to calculate the coefficient of determination (R²) of a simple linear regression. The first formula is specific to simple linear regressions, and the second formula can be used to calculate … See more You can interpret the coefficient of determination (R²) as the proportion of variance in the dependent variable that is predicted by the statistical model. Another way of thinking of it is … See more If you decide to include a coefficient of determination (R²) in your research paper, dissertation or thesis, you should report it in your results section.
