Nonparametric Clustering of Mixed Data Using Modified Chi-square Tests
Yawen Xu, Xin Gao, Xiaogang Wang
We propose a non-parametric method to cluster mixed data containing both continuous and discrete random variables. The product space of continuous and categorical sample spaces is…
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…
Tuning parameter selection for penalized likelihood estimation of inverse covariance matrix
Xin Gao, Daniel Q. Pu, Yuehua Wu +1
In a Gaussian graphical model, the conditional independence between two variables are characterized by the corresponding zero entries in the inverse covariance matrix. Maximum like…
