EMMAX-BN is the EMMAX using the Balding-Nichols kinship matrix among all individuals. GLS is the generalized least squares method accounting for half-sib intraclass correlation. PCA is the method of principal component analysis for stratification correction using to top 20 principal components as covariables. LS is the least squares method without stratification correction reported in Cole et al.[6]. LS_1494 is the LS analysis without the 160 elite cows.
