Abstract

In this paper, we address the problem of nonnegative estimation of variance components in multivariate unbalanced mixed linear models with two variance components, thus generalizing the results in Mathew et al. (J. Multivariate Anal. 5 (1994) 83). We illustrate our results with an example.
