Fig. 1From: A second-level diagonal preconditioner for single-step SNPBLUPEigenvalues of different preconditioned coefficient matrices \({\tilde{{\mathrm {C}}}}\) for the reduced dataset. Eigenvalues of the preconditioned coefficient matrices of ssSNPBLUP_MS are depicted on a logarithmic scale. All eigenvalues less than \(10^{-10}\) were set to \(10^{-10}\). Eigenvalues are sorted in ascending orderBack to article page
