From: Optimisation of the core subset for the APY approximation of genomic relationships
Predictive ability for the validation set in pigs. Accuracy is the correlation between genomic estimated breeding values (GEBV) and phenotypes adjusted for the fixed effects (\(\mathbf {y-Xb}\)). The GEBV were based on the full inverse (Full) or the Algorithm for Proven and Young (APY) inverse 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
