istribution (e.g. mean and median).</p>
<p>Often quite smaller ESS would be sufficient for the desired estimation
accuracy, but the estimation of ESS and convergence diagnostics
themselves require higher ESS. We recommend requiring that the
bulk-ESS is greater than 100 times the number of chains. For example,
when running four chains, this corresponds to having a rank-normalized
effective sample size of at least 400.</p>
