27. REML Estimation of Genetic Variances

Updated notes

Shayle Searle has just published some excellent notes (around 250 pages) that are a mathematical supplement to Henderson's classic book Applications of linear models in animal breeding. These are rather detailed and are quite informative.

Dr. L. R. Schaeffer (Department of Animal & Poultry Science, University of Guelph, Ontario) has an outstanding set on notes on advanced topics in Animal Models , which has much on variance component estimation.

Dr. Schaeffer also has an excellent set of notes on historical approaches to variance component estimation. We did not discuss many of these (Henderson's Methods 1-4, MIVQUE, Method R ) as they are not longer widely used, but are still occasionally seen in the literature.

Notes from Jim Fry on using SAS software to perform Restricted Maximum Likelihood (REML) Analysis of Quantitative-Genetic Data.
