mple if <span class="math inline">\(\hat{R}\)</span> is less than 1.01. Stan reports
<span class="math inline">\(\hat{R}\)</span> which is the maximum of rank normalized split-R-hat and rank
normalized folded-split-R-hat, which works for thick tailed
distributions and is sensitive also to differences in scale. For more
