# Do we want an [umvue] tag?

The tag has one question on it. Do we want to keep it going or not?

For those of us who are not familiar with UMVUEs (uniformly minimum-variance unbiased estimators), the long story short is that they are (in my opinion) the culmination of a statistical inference course when it comes to parameter estimation, particularly in graduate-level statistics. Because of this, one could argue that it should be synonymized with .

I have no strong preference for either option.

• My philosophy on tags is more "impromptu" than recent discussions of them seem to reflect. I see no harm in allowing users to introduce new tags (given sufficient reputation) when there is a perceived need, and let them prosper or fail for the better part of a month before taking Community action to eliminate or synonymize them. This is particularly so if the originator takes the time to write a nice Wiki and excerpt. – hardmath Jan 9 '19 at 19:23
• Not strictly relevant to our stance, but as might be expected CrossValidated has such a tag with a few dozen Questions. It could be used to model a Wiki here, if desired. – hardmath Jan 9 '19 at 19:32
• If there's only a dozen on CV about it I doubt we will get more here. – Alexander Gruber Jan 9 '19 at 19:50
• Some data on this site: "UMVUE" has appeared in 102 questions. – Eric Wofsey Jan 9 '19 at 20:06
• @hardmath: While I don't disagree, I also feel that this shouldn't be a reputation based privilege. Rather it should be based on experience with the tagging system, which is fragile already. – Asaf Karagila Jan 9 '19 at 21:18
• I have pinged the tag-creator with a comment linking to this post - it might be useful that they know about this discussion, too. – Martin Sleziak Jan 10 '19 at 8:36
• FWIW, there was an opinion in this post that there are too few tags relative to the number of posts we have, compared with other sites. Please see bullet number 7. This observation was made $3.5$ years ago, and I'm not sure if it was true back then or if it's still relevant now. – Lee David Chung Lin Jan 22 '19 at 15:26
