WebJul 22, 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 variation in the response variable around its mean. The mean of the dependent variable predicts the dependent variable as well as the regression model. WebIn statistics, the coefficient of determination, denoted R2or r2and pronounced "R squared", is the proportion of the variation in the dependent variable that is predictable from the independent variable(s).
