<p dir="auto">There is <code class="notranslate">mean</code>, <code class="notranslate">max</code>, <code class="notranslate">median</code>, <code class="notranslate">min</code> and <code class="notranslate">mad</code> yet no <code class="notranslate">mode</code> for <code class="notranslate">groupby</code> objects.  Is there a good reason?  What if I add and issue pull-request?</p>
