If R^2=0.81 in a regression analysis, what does this indicate?
If R² = 0.81 in a regression analysis, it means that 81% of the variation in the dependent variable is explained by the independent variable(s) in the model. This indicates a strong fit, showing that the model does a good job of predicting the outcome. The remaining 19% of the variation is due to other factors not included in the model or random error.
