<p>Let us split <code>moving-average</code> into <code>moving-average-filter</code> and <code>moving-average-model</code> and make nice Wiki excerpts warning not to confuse one with the other.</p>

<p>Pros: </p>

<ul>
<li>One tag name is not an extension of the other, thus limiting the confusion.</li>
</ul>

<p>Cons:</p>

<ul>
<li>The notion of <em>moving-average filter</em> may be unclear (although once the tag excerpt is read, it will hopefully be clear).</li>
<li><em>Moving-average model</em> itself is a filter just like <em>moving average</em>, although perhaps less known. Thus <code>moving-average filter</code> retains the ambiguity of the current <code>moving-average</code> tag.</li>
<li>The old <code>moving-average</code> tag can be reintroduced unless blacklisted, which is hard to achieve.</li>
</ul>
