From: Stand-level biomass models for predicting C stock for the main Spanish pine species
Mean errors for carbon estimates at plot level for the studied pine species throughout peninsular Spain according the four studied models. ME, mean error (in Mg·ha− 1 of C); MAE, mean absolute error (in Mg·ha− 1 of C); RMSE, Root mean square error (in Mg·ha− 1 of C); MPE, mean percentage error (in %); MAPE, mean absolute percentage error (in %); RMSE, Root mean square percentage error (in %)
