<p>With this post <a href="https://stats.stackexchange.com/questions/340468/partial-quantile-moments">Partial quantile moments?</a> there was introduced a new tag [partial-moments] (so far without tag wiki).  I think this (or some similar tag) could be useful, but my question is: What should its name be? What is this concept, as used in post such as <a href="https://stats.stackexchange.com/questions/191492/how-does-saddlepoint-approximation-work/191781#191781">How does saddlepoint approximation work?</a> or <a href="https://stats.stackexchange.com/questions/137931/when-would-we-use-tantiles-and-the-medial-rather-than-quantiles-and-the-median/142384#142384">When would we use tantiles and the medial, rather than quantiles and the median?</a> (where I used the name "cumulative expectation").  I's sure this tag could be useful on other posts as well.</p>

<p>I'm not sure if this should be posted here or on the main site, since the questions: What should the tag name be? and what is the "official name" (and some references, please) ? belongs on each site respectively!</p>
