Extended Data Fig. 10: Relation between yield potential uncertainty and environmental dissimilarity.
Relationship between spatially cross-validated root mean square errors (RMSE) and dissimilarity indexes between testing and training sites for each crop and water regime. Values were derived following the nearest-neighbor-distance-matching leave-one-out cross-validation (NNDM LOO CV) method10 and the dissimilarity index used to estimate the area of applicability of the metamodel11. This association was used to estimate the expected RMSE of yield potential predictions from the dissimilarity index between the prediction area and the training sites. Pearson correlation coefficients (r) and their P values are shown.
