<p>A <a href="https://stats.meta.stackexchange.com/q/1122/1036">very similar question</a> came up around a year ago, although I'm unaware of any material change in the site in response to that. I will suggest cardinal's suggestions are still just as relevant and highlight other communities' behavior in response to similar problems.</p>

<p>I think the faq tag <em>on the main site</em> is the simplest way forward. I imagine you have some answers of your own in mind about evaluating regression models: you could add a <code>faq</code> tag to the question yourself and then in the future make sure to link back to it whenever a similar question returns.</p>

<p>An interesting project may be to examine the network of answers and see which ones are linked to most frequently. These might be good candidates for applying the <code>faq</code> tag.</p>
