Calibration of Posterior Genotype Probabilities

Genotypes for chromosome 1 markers on the Illumina 550K chip, but not the Affymetrix 500K chip, were imputed with a phased reference panel of 60 individuals (HapMap CEU panel) in a sample of 1088 individuals genotyped on the Affymetrix 500K chip. Imputed genotypes are divided into bins according to their posterior genotype probability. The proportion of imputed genotypes that are consistent with the Illumina genotype are given for each bin. The line is the set of points with equal posterior genotype probability and accuracy rate.
