Composite likelihood may be useful for approximating likelihood based inference when the full likelihood is too complex to deal with. Stemming from a misspecified model, inference based on composite likelihood requires suitable corrections. Here we focus on the composite likelihood ratio statistic for a multidimensional parameter of interest, and we propose a parameterization invariant adjustment that allows reference to the usual asymptotic chi-square distribution. Two examples dealing with pairwise likelihood are analysed through simulation.

Abstract
Composite likelihood may be useful for approximating likelihood based inference when the full likelihood is too complex to deal with. Stemming from a misspecified model, inference based on composite likelihood requires suitable corrections. Here we focus on the composite likelihood ratio statistic for a multidimensional parameter of interest, and we propose a parameterization invariant adjustment that allows reference to the usual asymptotic chi-square distribution. Two examples dealing with pairwise likelihood are analysed through simulation.File in questo prodotto:
