<h3>Target Density</h3>
<p>The goal of sampling is to draw from a density <span class="math inline">\(p(\theta)\)</span> for
parameters <span class="math inline">\(\theta\)</span>. This is typically a Bayesian posterior
<span class="math inline">\(p(\theta|y)\)</span> given data <span class="math inline">\(y\)</span>, and in particular, a Bayesian posterior
coded as a Stan program.</p>
