Table 1.
Estimates (and SE) for the additive genetic (VA), permanent environment (VPE), and residual (V res) variance component, heritability (h 2) of egg‐laying date and accuracies of GEBVs from animal models with different relatedness estimators (Yang: following Yang et al. (2010), VanRaden: following VanRaden (2008), Yang‐ped: as Yang but scaled for pedigree, VanRaden‐ped, as VanRaden but scaled for pedigree)
| Relatedness estimator | VA | h 2 | VPE | V res | Accuracy | 95% CI | RMSE |
|---|---|---|---|---|---|---|---|
| Pedigree | 5.77 (1.72) | 0.24 (0.07) | 2.64 (1.71) | 15.7 (0.58) | 0.197 (0.045) | 0.115–0.281 | 4.723 |
| VanRaden | 3.91 (1.31) | 0.16 (0.05) | 4.48 (1.38) | 15.6 (0.58) | 0.210 (0.055) | 0.105–0.304 | 4.746 |

| VanRaden‐ped | 4.00 (1.33) | 0.17 (0.06) | 4.39 (1.39) | 15.6 (0.58) | 0.207 (0.054) | 0.104–0.304 | 4.745 |

The 95% confidence intervals of the accuracy as well as their root mean square error (RMSE) are also given.
