Evaluation of the phenotypic and genomic background of variability based on litter size of Large White pigs

Table 4 Correlations between log-transformed variance of litter size and EBV for LnVar^c and DHGLM^c obtained from three-fold cross-validation^a

Validation run	Correlations of ln(var(TNB))^b with
Validation run	EBV from LnVar^c	EBV from DHGLM^c
1	0.47	0.55
2	0.42	0.49
3	0.40	0.44
Average	0.43	0.49

^aThree-fold cross-validation was performed to compare the two methods used to obtain phenotypic variability of litter size: log-transformed variance of residuals (LnVar) and double hierarchical GLM (DHGLM)
^bLog-transformed variance of litter size per sow
^cEstimated in each run for 3650 sows with their records set to missing
