WebApr 13, 2024 · Polygenic risk scores (PRS) are now showing promising predictive performance on a wide variety of complex traits and diseases, but there exists a substantial performance gap across different populations. We propose ME-Bayes SL, a method for ancestry-specific polygenic prediction that borrows information in the summary statistics … Web3.2 Bayesian model averaging method. In the Bayesian Model Averaging (BMA) approach, given a few candidate parametric families, the posterior probabilities of the candidate models are used to quantify input uncertainty. Likewise, the posterior of distribution parameters is used to quantify the parameter uncertainty.

In the beta coin experiment, set n = 20 and p = 0.3, and set a = 4 and b = 2. Run the simulation 100 times and note the estimate of p and the shape and location of the posterior probability density function of p on each run.

Partitions: A collection of sets B 1,B 2,...,B n is said to partition the sample space S if the sets (i) are mutually disjoint and (ii) have as union the entire sample space. In particular, any set B, together with its complement Bc forms a partition of S.
