Median and 90% central confidence interval of differences between the bidimensional spline regression (splines) and bidimensional separable first-order autoregressive (AR) absolute metrics (i.e., |mSplines| − |mAR| for m equal to root mean square error of prediction of the expected phenotype -RMSE-; residual variance relative deviation -RVRD-; correlation between predicted and true simulated spatial effects -Scor-; and spatial variance relative deviation -SVRD-) by spatial range (short and long) and plot structure (design, single-tree plot -STP- and multiple-tree plot -MTP-). Positive (negative) values indicate a better performance by AR (splines), except for SCor where the relationship is the reverse
