Comparison of prediction accuracies across populations of the same ethnic group. The accuracies of HLA predictive models trained on samples from the WTCCC cohort (genotyped on Affy 500K) and validated on Caucasian samples in the FHCRC cohort (genotyped on Affy 5.0), and vice versa. Both observed and imputed HapMap SNPs were applied. The confidence threshold was set at CT = 0.
