Table 3 Correlation estimates (with SE) between the random effects on the level and the variance of litter size, estimated in Large White sows using a Double Hierarchical GLM (DHGLM) or conventional bivariate analysis

From: Genome-wide association study reveals novel loci for litter size and its variability in a Large White pig population
