WebJul 15, 2011 · The other major concern is potential bias in statistical test of GWAS, which can be conveniently examined using QQ-plot. We plotted quantiles of p values from our method against the quantiles of p values from standard haplotypes (Figure 3). The quantiles fit each other well. No obvious statistical bias was observed in the results from our method. WebAug 26, 2015 · Understanding Q-Q Plots.
