WebAug 24, 2024 · R Squared (also known as R2) is a metric for assessing the performance of regression machine learning models. Unlike other metrics, such as MAE or RMSE, it is not a measure of how accurate the predictions are, but instead a measure of fit. WebDec 5, 2024 · The R-squared, also called the coefficient of determination, is used to explain the degree to which input variables (predictor variables) explain the variation of output variables (predicted variables). It ranges from 0 to 1. For example, if the R-squared is 0.9, it indicates that 90% of the variation in the output variables are explained by ...

WebR 2 represents the proportion of total variability of the y -value that is accounted for by the independent variable x. For the specific case when there is only one independent variable X (i.e., simple linear regression), one can show that R 2 = r 2, where r is correlation coefficient between X and Y.
