as.commensurateEB: Convert RBesT mix object into a commensurateEB object

In wiesenfa/ESS: Quantification of prior informativeness in terms of prior effective and effective current sample size

Description

Convert RBesT mix object into commensurateEB object allowing the computation of empirical Bayes commensurate priors.

Usage

as.commensurateEB(prior)

Arguments

prior

An RBesT betaMix or normMix mixture object with a single mixture component

Value

A commensurateEB object which can be used in ecss. Note that for the normal-normal model, the empirical Bayes power and commensurate prior coincide (see Wiesenfarth and Calderazzo, 2019).
