<p>Years ago I reorganized the <code>[fisher]</code> tag.  I created several new tags (e.g., <code>[f-e]</code>, <code>[f-i]</code>, <code>[f-t]</code>, and <code>[r-f]</code>).  But I left the tag on ~25 threads that seemed to merit some connection to "fisher", but where idiosyncratic.  I edited the excerpt to put a rather specific message that the tag should only rarely be used, and the other tags should be preferred.  I think now that that strategy is unworkable and was a mistake.  Not surprisingly, perhaps, many people over the intervening years ignored that usage guidance, necessitating this thread.  </p>

<p>Over the past couple days, @mdewey, @amoeba (thanks, guys), and I have cleaned up the remaining <code>[fisher]</code> tagged threads.  In doing so, we have created <a href="https://stats.stackexchange.com/questions/tagged/fisher-scoring" class="post-tag" title="show questions tagged &#39;fisher-scoring&#39;" rel="tag">fisher-scoring</a> and <a href="https://stats.stackexchange.com/questions/tagged/fishers-lsd" class="post-tag" title="show questions tagged &#39;fishers-lsd&#39;" rel="tag">fishers-lsd</a>.  I also created two synonyms (noted in the body of the question above).  After 24 hours, <code>[fisher]</code> should disappear.  Let us hope it won't be recreated.  </p>
