The PPLD has advantages over conventional regression methods in application to moderately sized genome-wide association studies

Effects of decreasing minor allele frequency under H0.
Shown here are QQ plots comparing sampling distributions (N = 400) under H0 for minor allele frequency (MAF) = 0.4, 0.3, 0.2, 0.1 compared to the corresponding behavior with MAF = 0.5, for CPH-P and log10BR.
