Results on empirical power. Empirical power of the Armitage trend test and the Mantel statistic Using Haplotype Sharing for no (dots), differential (triangulars) and nondifferential (squares) genotype errors incorporated following the unrestricted misclassification model for different error rates per locus. With a small error rate of a) 0.2% both pointwise tests achieve a power of around 90–100%. With higher error rates of b) 8% or c) 15.6% the power is reduced for nondifferential genotyping errors.
