Validation of reaction norm breeding values for robustness in Australian sheep

Table 4 Correlations between reaction norm estimated breeding values (EBV) for sires and the realised regression of pre-corrected progeny phenotypes across the environmental covariable (EC)

Cross-validation results (Fold 1, 2, and 3 and average) and forward prediction are reported
\({\text{a}}_{0}\): sire EBV for intercept; \({\text{a}}_{1}\) sire EBV for slope; \({\text{a}}_{1}^{\text{*}}\): sire EBV for scale-corrected slope; \({\text{p}}_{{0}}\): realised progeny performance intercept; \({\text{p}}_{1}\): realised progeny peformance slope
