Table 1.
Posterior means and 95% credible intervals for model parameters under the moment and normal models for the nonnull effect sizes. Note that the interpretation of τ is not the same in the moment and normal models, whereas the remaining parameter values do have the same interpretation in each model. All results are based on 10 independent runs of an MCMC algorithm. Each run consisted of 105 burn-in iterations, followed by 106 parameter updates.
