Bayesian inference for normal multiple-trait individual-tree models with missing records via full conjugate Gibbs

Abstract: In forest genetics, restricted maximum likelihood (REML) estimation of (co)variance components from normal multiple-trait individual-tree models is affected by the absence of observations in any trait and individual. Missing records affect the form of the distribution of REML estimates of genetics parameters, or of functions of them, and the estimating equations are computationally involved when several traits are analysed. An alternative to REML estimation is a fully Bayesian approach through Markov chain Mon… Show more

“…The Bayesian approach has been used to genetically evaluate a range of different forest trees species (e.g. Sorya et al 1998;Cappa and Cantet 2006;Waldmann and Ericsson 2006). Variations of the Monte-Carlo Markov Chain (MCMC) such as Gibbs sampling algorithm have been shown to be appropriate for the analysis of ordered categorical data in breeding programs.…”

“…Alternatively, a full Bayesian approach by means of the Gibbs sampler can be attempted for estimating the (co)variance components for additive direct and indirect effects, by exploiting the similarity with the model of maternal effects (SORENSEN and GIANOLA, 2002, section 13.3). The basics of the Gibbs sampling is discussed by CASELLA and GEORGE (1992), whereas SORIA et al (1998), GWAZE and WOOLLIAMS (2001), ZENG et al (2004 and CAPPA and CANTET (2006) developed some applications of the sampler to the genetic improvement of forest trees. The goals of this research are: 1) to introduce an additive genetic individual tree model that includes direct and competition effects, accounting for the number and position of competitor trees; 2) to estimates the dispersion parameters of the model (additive variances for direct and competition effects, and the covariance between both effects) using a Bayesian approach by means of the Gibbs sampler.…”

“…Experimental evidence supporting Griffing's theory was obtained using the above experimental design in Drosophila melanogaster (Pé rez-Tome and Toro, 1982;Martin et al, 1988;Ló pezSuá rez et al, 1993) and Tribolium castaneum Toro, 1992 and. More sophisticated designs and analyses involving the estimation of variance components using mixed-model methodologies have been developed by Muir (2005), Van Vleck and Cassady (2005), Van Vleck and Cassady (2006), Cantet and Cappa (2008) and also implemented in Drosophila (Wolf, 2003), trees (Cappa and Cantet, 2006), (mussels (Brichette et al, 2001), poultry (Craig and Muir, 1989), cattle (Van Vleck et al, 2007) and pigs (Arango et al, 2005)). …”
