WebDetails. At high marker density, the relationship matrix is estimated as A = W W ′ / c, where W i k = X i k + 1 − 2 p k and p k is the frequency of the 1 allele at marker k. By using a normalization constant of c = 2 ∑ k p k ( 1 − p k), the mean of the diagonal elements is 1 + f (Endelman and Jannink 2012). The EM imputation algorithm ... WebRRBLUP and RRBLUP2 are no-frills computer programfor s (1) calculating genomewide marker effects, estimating the predictive ability by cross-validation, and (3) predicting the performance of a test population. Cross-validation is done by a delete-one procedure. Suppose there are 200 individuals in the training population.
