From: Optimisation of the core subset for the APY approximation of genomic relationships
Correlations between \(\mathbf {GEBV_{Full}}\) and \(\mathbf {GEBV_{APY}}\) for all animals and only validation animals in simulation. Genomic estimated breeding values (GEBV) were based on the full inverse (Full) or the Algorithm for Proven and Young inverse (APY) of the genomic relationship matrix (\(\mathbf {G}\)). For APY, the core subset was constructed at random (Random), based on the highest diagonal in \(\mathbf {G}\) (Diagonal), a combination of Random and Diagonal (Weighted), or the conditional algorithm (Conditional). Random and weighted constructions show five samples
