WebOct 1, 2015 · In R, you can make use of the CI.Rsq () function provided by the psychometric package. As for the formula it applies, see Cohen et al. (2003), Applied Multiple Regression/Correlation Analysis for the Behavioral Sciences, p. 88: S E R 2 = 4 R 2 ( 1 − R 2) 2 ( n − k − 1) 2 ( n 2 − 1) ( n + 3) Then, the 95% CI is your R 2 ± 2 ⋅ S E R 2. Share Cite 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 the R² of many types of statistical models. See more 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 … 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.
