Table 3 Percentage of valid simulation replicates across nsim=1000 replicates. Bayesian replicates were excluded if they yielded any divergent transitions, effective sample sizes were too low (below 400), or split-\(\hat {r}\) values were too large (above 1.01). REML replicates were excluded from calculations for \(\hat {r}\) if both cluster and cluster-period variances were estimated as 0, yielding an invalid estimate of r
