Published in 2020 at "Geomatics, Natural Hazards and Risk"

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.

Published in 2019 at "Statistica Sinica"

DOI: 10.5705/ss.202017.0220

Abstract: Logistic linear mixed models are widely used in experimental designs and genetic analyses of binary traits. Motivated by modern applications, we consider the case of many groups of random effects, where each group corresponds to… read more here.
