Genetic Groups in an Animal Model
TL;DR: Rules are presented for assigning coefficients to the genetic group portion(s) of the mixed model equations after transformation to solve directly for total genetic value (group plus animal solutions) simultaneously for sires and cows using an animal model.

Computing Strategies for Solving Mixed Model Equations
L.R. Schaeffer,B.W. Kennedy +1 more
TL;DR: Three approaches to constructing and solving sets of equations of large order are discussed and compared on the basis of number of data elements that must be processed by a computer program during a round of iteration of the solution phase.

Solution of multiple trait animal models with missing data on some traits.
Vincent Ducrocq,B. Besbes +1 more
TL;DR: A simple method based on an EM argument and replacing missing records by their expectation given the current parameters allows the use of the canonical transformation in situations where data are missing and selection is ignorable.
Computing solutions to mixed model equations.
Larry R Schaeffer,B.W. Kennedy +1 more
TL;DR: In this paper, a simple method for so-called mixed model equat ions of l arge order is presented and compared to a modified reduced animal model procedure for swine infrastructures.
