Restricted maximum likelihood estimates of variance components from multitrait sire models with large number of fixed effects

Restricted maximum likelihood estimates of variance components from multitrait sire models with large number of fixed effects

Journal of Animal Breeding & Genetics 106(6): 409-422

An expectation maximization algorithm to maximize multitrait REML equations was formally described. A computing strategy based on absorption of main fixed effects that allows unequal design matrices for different traits was presented with a small numerical example. Convergence of the method was compared to Henderson's EM-like algorithm by using dairy cattle reproduction data. Convergence rate determined as a round to round change in variance component solutions was about the same regardless of which algorithm was used.
