Performance of alternative spatial models in empirical Douglas-fir and simulated datasets

Table 3 Accuracy of prediction of breeding values from the block design (block), bidimensional separable first-order autoregressive (AR) and bidimensional spline regression (splines) models, and Spearman correlations coefficients between predicted breeding values of the 10% best candidates for all pairs of models. The corresponding traits analyzed are total height for sites 2.708.3 and 2.707.1, and diameter for site 3.704.2
