The comparisons were done at different FFs (row) and different coverages (column). The recorded power is at the type I error of 0.001.

BF Bayesian method,Z Z-test.

^aSimulated based on empirical data of chromosomes 13, 18, and 21.

^bBased on three 5-Mb regions each drawn from the three chromosomes.
