WebPRS-CSx couples genetic effects across populations via a shared continuous shrinkage (CS) prior, enabling more accurate effect size estimation by sharing information between summary statistics and leveraging linkage disequilibrium diversity across discovery samples, while inheriting computational efficiency and robustness from PRS-CS. WebIn this work, we investigate a specific continuous shrinkage prior. We assign an independent gamma-gamma prior on the local shrinkage parameter ψ j: ψ j Gða;δ jÞ; δ j Gðb;1Þ; ð9Þ where G(α,β) denotes the gamma distribution with shape parameter α and scale parameter β. By using change of variables, it can be verified that placing ... everland caribbean bay

WebWe propose a new class of priors for linear regression, the R-square induced Dirichlet Decomposition (R2-D2) prior. The prior is induced by a Beta prior on the coefficient of determination, and then the total prior variance of the regression coefficients is decomposed through a Dirichlet prior. We demonstrate both theoretically and empirically the … WebFit a linear or logistic regression model using Bayesian continuous shrinkage prior distributions.
