mashr: Multivariate Adaptive Shrinkage in R. This package implements methods to estimate and test many effects in many conditions (or many effects on many outcomes). Empirical Bayes methods are used to estimate patterns of similarity among conditions, then exploit these patterns of similarity among conditions to improve accuracy of effect ...

Oct 17, 2016 · And analogous ideas can be used to perform EB inference for variances (Lu and Stephens, 2016). Importantly, and perhaps surprisingly, our work demonstrates how EB inference under a general UA is, if anything, computationally simpler than commonly used more restrictive assumptions—such as a spike and slab or Laplace prior distribution ( Johnstone and Silverman, 2004 )—as well as being more flexible.
We have also worked on methods for testing these imputed variants, taking account of the uncertainty in the predicted genotypes (Servin and Stephens, Guan and Stephens). Somewhat surprisingly, it turns out that satisfactory results can often be obtained by simply replacing imputed genotypes with a point estimate - the posterior mean - and then performing a simple regression-based analysis of phenotype on the resulting imputed genotypes.
