Cross-validation of best linear unbiased predictions of breeding values using an efficient leave-one-out strategy.

Journal of animal breeding and genetics = Zeitschrift fur Tierzuchtung und Zuchtungsbiologie - 1 Sept 2021

Cheng Jian, Dekkers Jack C M, Fernando Rohan L

Abstract excerpt

Empirical estimates of the accuracy of estimates of breeding values (EBV) can be obtained by cross-validation. Leave-one-out cross-validation (LOOCV) is an extreme case of k-fold cross-validation. Efficient strategies for LOOCV of predictions of phenotypes have been developed for a simple model with an overall mean and random marker or animal genetic effects. The objective here was to develop and evaluate an...
