Abstract/Description: | For the half-sib model, we know that the unbiased estimator for 'between sire' variance component (0';) may take negative values. If, one attempts to restrict the value of 0'; to be non-negative then this will destroy its unbiasedness property and more importantly, further complicates the distribution theory ofa;. A second difficulty is the sensitivity of inferences to departure from underlying assumptions. To overcome these difficulties, following Box and Tiao (1975) Bayesian approach has been adopted to estimate the variance components cr; and 0';. Kumar et al. (2004) obtained Bayesian estimates of heritability in animal breeding experiment. Bayesian analysis of data involves treating the parameters as random variables and finding their joint posterior distribution given the data. The joint distribution of the unknown random variables and the data (y) can be written as p(y, IJ, cr;, 0-;) =P(ylll, cr~, cr;) p(IJ) p(0';, cr~) |
