<h3><span class="header-section-number">16.4.3</span> Estimation of MCMC Standard Error</h3>
<p>The posterior standard deviation of a parameter <span class="math inline">\(\theta_n\)</span> conditioned on observed data <span class="math inline">\(y\)</span> is just the standard deviation of the posterior density <span class="math inline">\(p(\theta_n | y)\)</span>. This is estimated by the standard deviation of the combined posterior draws across chains,</p>
