<p>Let us keep <code>moving-average</code> for <em>moving average</em> (and include a warning about its use in the Wiki excerpt) and retag questions about <em>moving-average model</em> (MA(q) model) as <code>arima</code>.</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>No separate tag for <em>moving-average model</em> (unlike <em>autoregression</em>).</li>
</ul>
