DOI: 10.1080/19475705.2020.1785955
Abstract: Abstract A difficulty in variance component estimation (VCE) is that the estimates may become negative, which is not acceptable in practice. This article presents two new methods for non-negative VCE that utilize the expectation maximization… read more here.
