Eigenvalues of different preconditioned (deflated) coefficient matrices for the reduced dataset. Eigenvalues of the preconditioned coefficient matrices of ssGBLUP and of ssSNPBLUP, and of the preconditioned deflated coefficient matrix of ssSNPBLUP with one SNP effect per subdomain are depicted on a logarithm scale. All eigenvalues less than 10−11 were set to 10−11. Eigenvalues are sorted in ascending order
