Predictive ability for crossbred animals in the validation population

	Nogen	Gen_AM	Gen_ADM
$cor\left(y_c,\widehat{y}\right)$ a	0.010 (0.031)	0.056 (0.031)	0.056 (0.031)
Regression coefficientb	0.703 (2.218)	0.736(0.386)	0.730 (0.385)

Numbers between brackets are the standard errors of the corresponding parameters

^aPredictive ability ($\text{cor}\left({\text{y}}_{\text{c}},\widehat{y}\right)$) is given by the correlation coefficient between the corrected phenotypes ($y_c$) and their predictions ($\widehat{y}$) for total number of piglets born (TNB) in crossbred animals

^bRegression coefficient of the corrected phenotypes ($y_c$) on the predicted observations ($\widehat{y}$) in crossbred animals
