Multiple R vs. R-Squared: What
WebMar 8, 2024 · R-squared evaluates the scatter of the data points around the fitted regression line. It is also called the coefficient of determination, or the coefficient of multiple determination for multiple regression. For the same data set, higher R-squared values represent smaller differences between the observed data and the fitted values. WebR-squared measures the strength of the relationship between the predictors and response. The R-squared in your regression output is a biased estimate based on your sample.
