"WebMar 4, 2024 · What is R-Squared? R-Squared (R² or the coefficient of determination) is a statistical measure in a regression model that determines the proportion of variance in the dependent variable that can be explained by the independent variable. In other words, r-squared shows how well the data fit the regression model (the goodness of fit). Figure 1. " - Goodness of fit econometrics
