Say, I have two tissues, from each one I called eQTLs, with effect sizes and p-values. My question is, how to find eQTLs only exist in tissue A, but not B. Obviously, a simple comparison is not appropriate, because "not detected" as an eQTLs in one tissue does not mean it is not (it could simply be lack of power).
I would think it as some sort of meta analysis and thus have checked some papers, but couldn't find what I want. Could anyone suggest a test, or a paper doing that, or a package? My feeling is that this question fits better in the bayesian framework? Thanks.
