<p>I don't think that would be a good idea - "GMM" is a little ambiguous and could mean Gaussian Mixture Model, which is currently tagged <code>gaussian-mixture</code>.</p>

<p>Nothing wrong with adding <code>growth-mixture-model</code> as a tag though.  It looks like there already exists <code>growth-model</code> which has been used on growth mixture models in the past.</p>

<p>I've created <code>growth-mixture-model</code> as a new tag.  I don't know if it should be as synonym of <code>growth-model</code> or if it is a special case.</p>
