d warmup draws are written to the CSV output file
directly after the CSV header line.
Since the default option is <code>save_warmup=0</code>, this section is
usually not present in the output file.</p>
<p>Here we specified <code>num_warmup=200</code> and left <code>thin</code> at the default value <span class="math inline">\(1\)</span>,
therefore the next 200 lines are data rows containing
the sampler and model parameter values for each warmup draw.</p>
