Statistical power comparison at a minor allele frequency of 0.1 (common variant minor allele frequency). Barplot depicting the statistical power comparison between the joint score test method and other methods such as MetaTissue model (Fixed Effects, FE; Random Effects, RE) and eQTL-BMA when the (a) number of tissues is 5 and (b) 10 at a minor allele frequency of 0.10. We varied the proportion of variance explained by γ(P V E _γ) between 0 - 25 % and β fixed effect for the additive effect of the SNP. Each vertical grid labeled 0 through 25 represents varying levels of P V E _γ whereas each horizontal grid represents the presence or absence of the additive effect due to SNP
