R-Squared - Meaning, Regression, Examples, Interpretation, vs R

WebMar 8, 2024 · R-squared is the percentage of the dependent variable variation that a linear model explains. R-squared is always between 0 and 100%: 0% represents a model that does not explain any of the variations in the response variable around its mean. The mean of the dependent variable predicts the dependent variable as well as the regression model.
