From: Strategies and utility of imputed SNP genotypes for genomic analysis in dairy cattle
Mean allelic error rate (%) of imputing high density SNPs (800K) using different number of SNPs in the test set by 2-tiered and 3-tiered approach. Scenario (a) included 425 reference and 420 test animals, scenario (b) included 41 reference and 420 test animals. In the 3-tiered approach, an additional set of 2205 bulls with 50K data is included as middle tier in both scenarios (a) and (b). The results shown are for chromosome 20.
