Bayesian model selection approach for colored graphical Gaussian models
Qiong Li, Xin Gao, Helene Massam
We consider a class of colored graphical Gaussian models obtained by placing symmetry constraints on the precision matrix in a Bayesian framework. The prior distribution on the pre…

Approximate Bayesian estimation in large coloured graphical Gaussian models
Qiong Li, Xin Gao, Helene Massam
Distributed estimation methods have recently been used to compute the maximum likelihood estimate of the precision matrix for large graphical Gaussian models. Our aim, in this pape…

Bayesian precision matrix estimation for graphical Gaussian models with edge and vertex symmetries
Helene Massam, Qiong Li, Xin Gao
Graphical Gaussian models with edge and vertex symmetries were introduced by \citet{HojLaur:2008} who also gave an algorithm to compute the maximum likelihood estimate of the preci…
