“…For instance, this has lead to the investigation of integrated likelihood functions for non-Bayesian inference (Liseo, 1993, Berger et al, 1999, Severini, 2007, 2010, 2011, to the development of matching priors that ensure approximate frequentist validity of posterior credible regions (see e.g. Datta and Mukerjee, 2004), to the use Bayesian expansions for frequentist computations (see, for instance, Mukerjee and Reid, 2000), and to the use of pseudo-likelihood functions for Bayesian inference (see, among others, Severini, 1999 In particular, the agreement between the frequentist and posterior coverage probabilities of credible regions, arising from matching priors on ψ only derived from L mp (ψ), provides a validation for these priors, and hence their study is of interest from the frequentist viewpoint as well.…”
