<h2><span class="header-section-number">3.3</span> Sliced Missing Data</h2>
<p>If the missing data are part of some larger data structure, then it can

Here’s an example for time-series data, where only some entries in the
series are observed.</p>
<pre><code>data {
  int&lt;lower = 0&gt; N_obs;
  int&lt;lower = 0&gt; N_mis;
  int&lt;lower = 1, upper = N_obs + N_mis&
