How to Interpret RMSE. RMSE is a useful way to see how well a model is able to fit a dataset. The larger the RMSE, the larger the difference between the predicted and observed values, which means the worse a model fits the data. Conversely, the smaller the RMSE, the better a model is able to fit the data.
