A random regression model can be used to fit repeated measurements such as weight gain of an animal over time in order to accommodate the between- and within-individual variations. The Bayesian approach is an alternative to the REML-BLUP approach for drawing inference and often depends on Markov chain Monte Carlo (MCMC) methods. Our studies primarily focus on the efficiency of MCMC methods in models for repeated measurements in time. Efficient methods should make Bayesian methods feasible in studying animal growth traits.

520 $a A random regression model can be used to fit repeated measurements such as weight gain of an animal over time in order to accommodate the between- and within-individual variations. The Bayesian approach is an alternative to the REML-BLUP approach for drawing inference and often depends on Markov chain Monte Carlo (MCMC) methods.

520 $a With conjugate prior distributions, posterior samples under the random regression model can be obtained with Gibbs sampling algorithm. Orthogonality of parameters can reduce posterior correlations among model parameters and therefore improve convergence rate of MCMC methods. Hierarchical centering can improve the convergence rate of MCMC methods when the variance of the random effects is much larger than the variance of the residuals. Adopting hierarchical centering and orthogonality simultaneously yields the greatest improvement in convergence rate. When there are more than one random component besides random residuals, using a cycling algorithm along with orthogonal polynomials leads to the best performance. In addition, using a batching scheme for drawing correlated parameters can improve convergence rate as well.
520 $a It is also possible to develop Metropolis-Hastings (M-H) algorithms for nonlinear models. We find that M-H algorithms with a normal jumping distribution, that is centered at the current value and with its variance evaluated either at individual-model-fitting MLE or at the current value, perform best.
