# Why there are no tags for score-test and nuisance parameter or wikipedia?

Why not add tags for Rao's score-test and nuisance-parameter?

Some questions are about wikipedia.org definitions. Why not introduce a wikipedia.org tag?

• Tags are created by users, I think. If nobody's seen fit to tag their question with that, it won't exist. As for a wikipedia tag, I don't think it would serve much purpose - why do we need to group questions that refer to wikipedia? It would be like having a google tag, too generic to be useful.

Anyone with the create tags privilege can create a new tag, although some created tags are later merged into others or deleted. When someone perceives the need for a tag, they type a new name in the tags field when asking or editing a question and the tag is created. This can be done by the original asker, by someone answering the question, or by someone editing the thread and maintaining the tidiness of the site.
Be aware that the site has been around for ~13.5 years and has had more than ~200k questions posted. There may be 1570 tags currently. If a tag doesn't exist right now, that is prima facie evidence that it may not be needed. While that's certainly not absolute, we recently had SE raise the reputation threshold for creating new tags, because so many of the new tags created at this point need to be merged or deleted (cf., Increasing reputation needed for creating tags?). For example, I'm open to considering an argument that a [score-test] and/or [nuisance-parameter] tag would be helpful, but I agree with @mkt's comment that a [wikipedia] tag would not be useful and I would quickly delete it, if I saw it created.
