The multivariate linear model with multivariatet and intra-class covariance structure

The prediction distribution of future responses from a multivariate linear model with error having a multivariatet-distribution and intra-class covariance structure has been derived. The distribution depends on ρ, the intra-class correlation coefficient. For unknown ρ, the marginal likelihood function of ρ has been obtained and the prediction distribution has been approximated by the estimate of ρ. As an application, a β-expectation tolerance region for the model has been constructed.
