From: How scale affects N2O emissions in heterogeneous fields of a diversified agricultural landscape
Output of the RF model aiming to explain variations in mean daily N2O-N emissions of each micro plot. (a) Model validation of the full dataset is displayed with a 1:1 line as reference to the regression line. R2, RMSE and MAE, 95% confidence interval (CI) and regression equation (y) from the regression of actual vs. predicted values are displayed. Specific variables of the RF model are displayed in the black box. (b) Predictive RF model using tenfold cross validation is displayed with a 1:1 line as reference to regression line. (c) Variables of importance are plotted against their increase in MSE (%) value for the RF model.
