Gaussian variational approximation with composite likelihood for crossed random effect models

Libai Xu, Nancy Reid, Dehan Kong

Composite likelihood usually ignores dependencies among response components, while variational approximation to likelihood ignores dependencies among parameter components. We deriv…

Note on information bias and efficiency of composite likelihood

Ximing Xu, Nancy Reid, Libai Xu

Does the asymptotic variance of the maximum composite likelihood estimator of a parameter of interest always decrease when the nuisance parameters are known? Will a composite likel…
