Genomic selection using a fast EM algorythm. 1. Understanding the methodology

R.K. Shepherd, J.A. Woolliams

Research output: Contribution to conferenceAbstract


The paper uses the technical computer software Mathematica© to explain the features inherent in the procedure emBayesB which is a fast EM algorithm for implementing genomic selection by mapping QTL in genome-wide dense SNP marker data. The prior mixture for a SNP effect and the bimodal shape of the posterior distribution of a SNP effect are displayed graphically, along with visualisations and calculations of how emBayesB estimates genomic breeding values. The companion paper (Shepherd et al. 2009) uses emBayesB to analyse simulated data.
