and Bartlett corrections are derived. These
approximations are modifications of formulae based on
signed root loglikelihood ratios obtained in Sweeting (1996) and are designed to address two problems
that arise in the practical application of these formulae in the
multiparameter case. The first problem is a computational
one associated with inversion of signed root loglikelihood
ratios. The second concerns the form of the posterior
expectation formula, which is not in a particularly convenient
form for the computation of predictive densities. The theory is
illustrated by two examples.</style></abstract></record></records></xml>
