We already have a thread for proposing candidates for tag synonyms, but there doesn't seem to be a similar thread for proposing tags for deletion. Similarly to the "synonym" thread, let's use this one to post proposals for tags deletions in answers, so to vote and discuss about them below the answers (rather than by opening new threads).


Now I am a moderator and I just got informed that moderator can't remove a tag, it can be done only by removing it from all the questions associated with it.

    $\begingroup$ I welcome this thread. The correct SE-term for tag deletion is "burnination". Mods do not have power to burninate a tag (i.e. to automatically remove it from all threads without pushing them to the front page), so the protocol for burnination is that mods should let SE admins know and the admins do it. As far as I know, no tag has ever been burninated this way on CrossValidated. $\endgroup$ – amoeba Mar 25 '16 at 15:25

    $\begingroup$ One more thing: before burninating a tag, one should better make sure that there are no threads where this is the only tag. If there are, then those should be edited to add some more relevant tags. I'd suggest that whoever proposes a tag deletion should take the responsibility of doing that first. After checking that this tag is never alone, please mention it in the corresponding answer. $\endgroup$ – amoeba Mar 25 '16 at 15:34

    $\begingroup$ I sometimes see new tags that are obvious typos for existing tags, I just nuke them immeadiately. $\endgroup$ – kjetil b halvorsen Jun 14 '17 at 12:29
  • $\begingroup$ Congratulations with the diamond, @Tim! I've been away during the final stages of the election and saw the results only today. I'm wondering if you have plans to get some tag burnination going. $\endgroup$ – amoeba Sep 2 '17 at 21:52
  • $\begingroup$ @amoeba thanks! First I'd need to learn how exactly mod can burinate a tag and then I'd do something with it. $\endgroup$ – Tim Sep 3 '17 at 9:47
  • $\begingroup$ @amoeba FYI: I just got informed that a moderator can't delete a tag, it can be done only by removing it from all the questions associated with it. $\endgroup$ – Tim Sep 3 '17 at 11:26
  • $\begingroup$ I am aware that mods cannot delete tags themselves; however, they can request SE admin team to delete a tag (this is called "burnination") and it is routinely done on other SE sites. So your information is not complete: there is a way that a mod (e.g. you) can make a tag be deleted. See meta.stackoverflow.com/tags/burninate-request/info and links there. $\endgroup$ – amoeba Sep 3 '17 at 14:31
  • $\begingroup$ @amoeba I went through the tags, in most cases it is not so many questions tagged by them, so we could probably deal with them by un-tagging the questions. I'm not sure if it is worth to ask CMs for this. $\endgroup$ – Tim Sep 4 '17 at 13:32

    $\begingroup$ That is fair enough, but e.g. [basic-concepts] has 200+ threads (see stats.meta.stackexchange.com/questions/2854) and manually untagging is not very attractive. $\endgroup$ – amoeba Sep 4 '17 at 15:14
  • $\begingroup$ @Tim, shall I delete my answer below, as the tag is now gone? (That is how I've handled the related thread on tag synonyms.) $\endgroup$ – gung Sep 10 '17 at 1:46
  • $\begingroup$ @gung There are eight implemented answers already deleted here so I assumed we are following the same principle as in the synonym thread. $\endgroup$ – amoeba Sep 11 '17 at 7:49

Turns out that we have a tag. Its wiki excerpt says

For questions about statistical theory. Always include a more specific tag as well.

This means that it is a meta tag by definition. And so it should go. It does not seem to add any value, is used inconsistently, and is only causing confusion.

  • $\begingroup$ If I recall correctly, there was discussion on Meta that this tag is actually useful (but I can't find it now). See also here for pourpose of creating it: meta.stats.stackexchange.com/questions/441/… $\endgroup$ – Tim Aug 2 '16 at 11:25
  • $\begingroup$ Well, that comment is from 2010 and does not seem very relevant to me anymore. Take a moment to look at the threads tagged with [theory] and you will see that this tag can be removed from any of them without any loss; there is always a better more specific tag(s). $\endgroup$ – amoeba Aug 2 '16 at 11:27

with 22 Qs and no wiki excerpt should be eliminated, partially by being replaced with (145), partially by simply being removed.

Currently people use it for questions like "How is independent T-Test valid for unequal samples?" or "Is the following inequality correct? How to prove it?" This does not make sense.


We have a tag, with 26 threads, and no excerpt or wiki. Some of the questions are clearly about the intra-class correlation, but others may be about other topics. The current threads could be retagged, and [repeatability] can be deleted automatically after 24 hours.
