<p>We have <a href="https://stats.stackexchange.com/search?q=%22absolute+value%22+distribution+is%3Aq">a number of questions on absolute values of random variables</a>, e.g.</p>

<ul>
<li><a href="https://stats.stackexchange.com/q/466428/1352">Expected value of the absolute standardized t distribution</a> (this is what motivates this question)</li>
<li><a href="https://stats.stackexchange.com/q/279220/1352">What is the expectation of the absolute value of the Skellam distribution?</a></li>
</ul>

<p>Somewhat to my surprise, we don't seem to have an <a href="https://stats.stackexchange.com/questions/tagged/absolute-value" class="post-tag" title="show questions tagged &#39;absolute-value&#39;" rel="tag">absolute-value</a> tag that would allow searching for questions that carry this tag and, say, the <a href="https://stats.stackexchange.com/questions/tagged/t-distribution" class="post-tag" title="show questions tagged &#39;t-distribution&#39;" rel="tag">t-distribution</a> or <a href="https://stats.stackexchange.com/questions/tagged/skellam" class="post-tag" title="show questions tagged &#39;skellam&#39;" rel="tag">skellam</a> one.</p>

<p>In fact, the sheer desirability of such a tag seems so obvious to me that I am sure I am missing something. So: what argues against such a tag? Or should we create it and start (judiciously) retagging?</p>
