Multiple-Trait Analysis Using Bayesian Methods In Animal Breeding: A Gibbs Sampling Approach, Mehmet Zi̇ya Firat Jan 2001

Multiple-Trait Analysis Using Bayesian Methods In Animal Breeding: A Gibbs Sampling Approach, Mehmet Zi̇ya Firat

Turkish Journal of Veterinary & Animal Sciences

Most animal breeding experiments are based on more than one economically important trait measured in each individual. In the statistical analysis of the resulting data, traits recorded in the same individuals are often considered one at a time. Usually we are interested, however, not only in the mode of inheritance of a particular trait but also in its relationships with other traits. Multivariate analyses are required to make inferences about genetic and phenotypic correlations between traits, but point estimates of such parameters can be poor even when breeding data on hundreds of animals are used. Bayesian methods exclude variance matrices …
