Simultaneous Model Selection and Estimation for Mean and Association Structures with Clustered Binary Data

Xin Gao, Grace Y. Yi

This paper investigates the property of the penalized estimating equations when both the mean and association structures are modelled. To select variables for the mean and associat…

Composite likelihood estimation of sparse Gaussian graphical models with symmetry

Xin Gao, Helene Massam

In this article, we discuss the composite likelihood estimation of sparse Gaussian graphical models. When there are symmetry constraints on the concentration matrix or partial corr…
