## Figure 4.
QQ-plots comparing the null distribution of the test statistic of interest with a
. Each column corresponds to a different test statistic: (1) χ^{2}(1) distributionG-statistic computed using the true genotypes (True); (2) G-statistic computed using called genotypes without filtering (Call NF); (3) G-statistic computed using called genotypes with filtering (Call F); and (4) the likelihood
ratio test statistic with unknown minor allele (LRT). Assuming 500 cases and 500 controls,
under the null hypothesis, a set of 5,000 sites were simulated with a MAF of 5% with
a sequencing depth of 2× (upper panels) and 5× (lower panels). The "Inflation" factor
[44] is shown in the upper left corner of each figure.
