| Abstract: | Analysis of covariance in designed experiments has a long history dating back to the middle of the twentieth century. Given the popularity of Bayesian approaches to statistical modelling and inference, it is somewhat surprising that there is so little literature on the application of Bayesian methods in this context. This paper proposes methods based on a recent formulation of the problem in terms of a multivariate variance components model which allows for a conjugate Bayesian analysis of balanced randomized block experiments with concomitant information. The analysis is complicated by a linear constraint involving two covariance matrices. Two solutions are proposed and implemented using Markov chain Monte Carlo methods. |
