The Dimensionality of Genomic Information and Its Effect on Genomic Prediction

Ivan Pocrnic, Daniela A. L. Lourenco, Yutaka Masuda, Andres Legarra, Ignacy Misztal
2016 Genetics  
Theory for the APY assumes that the optimal size of the subset (maximizing accuracy of genomic predictions) is due to a limited dimensionality of the GRM, which is a function of the effective population  ...  Most information in the GRM is contained in N e L largest eigenvalues, with no information beyond 4N e L.  ...  This research was primarily supported by grants from the Holstein Association USA (Brattleboro, VT), the American Angus Association, Zoetis, Cobb-Vantress, Smithfield Premium Genetics, the Pig Improvement  ...
