[HTML][HTML] Accuracy of genome-enabled prediction in a dairy cattle population using different cross-validation layouts
MA Pérez-Cabal, AI Vazquez, D Gianola… - Frontiers in …, 2012 - frontiersin.org
The impact of extent of genetic relatedness on accuracy of genome-enabled predictions was
assessed using a dairy cattle population and alternative cross-validation (CV) strategies
were compared. The CV layouts consisted of training and testing sets obtained from either
random allocation of individuals (RAN) or from a kernel-based clustering of individuals using
the additive relationship matrix, to obtain two subsets that were as unrelated as possible
(UNREL), as well as a layout based on stratification by generation (GEN). The UNREL …
