<p>As an example, we’ll consider the bivariate distribution, which is
easily marginalized. The coding here is brute force, representing
both an array of vector observations <code>y</code> and a boolean array
<code>y_observed</code> to indicate which values were observed (others can
have dummy values in the input).</p>
<pre><code>vector[2] y[N];
int&lt;lower=0, upper=1&gt; y_observed[N, 2];</code></pre>
<p>If both components are observed, we model them using the fu
