WebJan 22, 2010 · Background: In genomic selection, a model for prediction of genome-wide breeding value (GBV) is constructed by estimating a large number of SNP effects that are included in a model. Two Bayesian methods based on MCMC algorithm, Bayesian shrinkage regression (BSR) method and stochastic search variable selection (SSVS) … Websaturated models. Bayesian mapping [3–7] deals with large models more efficiently through the reversible jump Markov chain Monte Carlo (RJMCMC) [4], the shrinkage analysis [8, 9], or the stochastic search variable selection (SSVS) [10]. Shrinkage mapping and SSVS are more efficient in terms of whole genome evaluation because they are ...
