Table 3. Posterior means and 95% highest posterior density intervals (HPD; in parenthesis) for heritability estimates, genetic and phenotypic correlations obtained with the four models considered in the study and mean correlation between individual EBVs obtained from five sub-dataset samples for each model.

h2D is the direct heritability for social dominance (measured as a ratio of direct variance on the total phenotype, as is the indirect heritability
, and h2TOT is the TBV computed as
raD,C is the genetic correlation for direct and indirect effects (that is, σaD,C/(σ2aDσ2aC)0.5), rPeD,C is the phenotypic correlation for the same components, calculated as
rEBV is the average correlation between direct EBVs estimated from five sub-datasets (that is, 13 610±236 data) obtained after retaining about half of the dataset (that is, 5452±33 cows). ±Correlations were carried out on the EBV of individuals shared by each sub-dataset (that is, 2902±36 cows) and were averaged for each model.
