Power to detect selection from single-site statistics for various demographic models with a constant recombination rate. All statistics perform well under all 4 population histories. The only statistic notably sensitive to population history was iHS, which performed particularly well in models with expansion and relatively worse in models with bottlenecks and migration. The simulated region was 1 Mb in length with an equal proportion of allele frequencies 0.2, 0.4, 0.6, and 0.8 for the favored allele at a significance level of 0.01.
