RMSE vs R-squared - Data Science Stack Exchange

Web24 de abr. de 2024 · A higher R-squared value indicates a higher amount of variability being explained by our model and vice-versa. If we had a really low RSS value, it would mean that the regression line was very close to the actual points. This means the independent variables explain the majority of variation in the target variable. Web29 de ago. de 2024 · This will also say how well can two models perform on unseen data but R-squared only says information about model fit it gives no information about how model will perform on unseen data.
