WebJan 10, 2024 · Model performance across methodologies and data types. a) The RMSE of the testing set is shown for each data grouping (panels a–d) and class of model. Lower values indicate better model performance. As the data were centered and scaled RMSE is expressed in standard deviations of yield in the training set, i.e. ∼48.169 bushels per acre. WebThe RMSE will always be larger or equal to the MAE; the greater difference between them, the greater the variance in the individual errors in the sample. If the RMSE=MAE, then all …
