Table 1.

Model mean posterior estimates (on the liability scale), lower and upper 95% credible intervals, and number of effective samples (N_eff) for the initial univariate generalized animal model on migration phenotype binaries of 663 Atlantic salmon individuals from 32 half-sib families. Variances were modelled as either diagonal (tanks, residuals) or unstructured (dams, animals) covariance matrices for the two temperature environments. Residual variance was fixed to 1 in each environment, resulting in scaling of all components relative to the residual variance. Effects or variances different from zero (i.e. credible interval not including zero) are in italics.
