R-Squared Definition
WebAug 3, 2024 · R-squared, often written as r2, is a measure of how well a linear regression model fits a dataset. In technical terms, it is the proportion of the variance in the response variable that can be explained by the predictor variable. The value for r2 can range from … WebThe definition of R-squared is fairly straight-forward; it is the percentage of the response variable variation that is explained by a linear model. Or: R-squared = Explained variation / Total variation. R-squared is always between 0 and 100%: 0% indicates that the model … WebMay 20, 2024 · Add a regression equation and R² in ggplot2.
