Spearman correlations per week and per line between phenotypes^a (dashed lines) and estimated breeding values^b (solid lines) for RFI obtained with the phenotypic regression and the multi-SAD regression models. ^aFor week j, \(\rho \left( {\widehat{RFI}_{.j} ,\widehat{RFI}_{.j}^{*} } \right)\) where phenotypes of animal \(i\) at week \(j\) are \(\widehat{RFI}_{ij} = \hat{u}_{RFI,ij} + \hat{e}_{RFI,ij}\) and \(\widehat{RFI}_{ij}^{*}\) = \(\hat{u}_{RFI,ij}^{*} + \hat{e}_{RFI,ij}^{*}\) for the phenotypic regression and multi-SAD regression models, respectively. ^bFor week j, \(\rho \left( {\hat{u}_{.j} ,\hat{u}_{.j}^{*} } \right)\) where \(\hat{u}_{RFI,ij}\) and \(\hat{u}_{RFI,ij}^{*}\) correspond to the estimated breeding values for RFI for animal \(i\) at week \(j\) obtained with the phenotypic regression and multi-SAD regression models, respectively. Correlations calculated for 1229 phenotyped animals for the low RFI line and 1122 phenotyped animals for the high RFI line. Shaded area = 95% confidence interval
