Dominance and epistatic genetic variances for litter size in pigs using genomic models

Table 2 Predictive ability of phenotype for different models

Model	G^*	GD^**	GDI^***
\(cor\left( {y^{*} ,\hat{y}} \right)\) ^a	0.135	0.136	0.136
Regression coefficient^b	0.896	0.922	0.978

^aPredictive ability \(\left( {cor\left( {y^{*} ,\hat{y}} \right)} \right)\) is measured as the correlation between the corrected phenotypic observation \(\left( {y^{*} } \right)\) and the predicted corrected observation \(\left( {\hat{y}} \right)\)
^bRegression coefficients of \(y^{*}\) on \(\hat{y}\)
* G is for the additive model, **GD is for the \(A + D\) model, *** GDI is for the \(A + D + AA + AD + DD\) model
