Root mean square error calculation
Web10 Jan 2024 · The mean squared error calculates the average of the sum of the squared differences between a data point and the line of best fit. By virtue of this, the lower a mean sqared error, the more better the line represents the relationship. We can calculate this line of best using Scikit-Learn. WebThe results of the three evaluation metrics ( MSE, RMSE and MAE) are the same in both methods .You can use any method (manual or sklearn) according to your convenience in your Regression Analysis.
