I've only just really noticed the students-t tag.
It has no tag wiki and appears to be being used for both the t-test and the t-distribution (with, at a quick glance, more using it to refer to the test). It is used in fewer posts to refer to the test than t-test and in fewer posts that refer to the distribution than t-distribution. I don't see a clear purpose to it outside those meanings. About 2/3 of its uses have been this year (7 and a bit months); for some reason it seems suddenly popular.
My suggestion: I think (i) any references to Student's t-distribution under
[students-t] should be changed to
[t-distribution]; and then (ii)
[students-t] should become a synonym of
Given that it involves more than a handful of changes and its total number of uses is about the same as for
[t-test], I thought I should ask for views on this before doing anything hasty. What do you think?
(I haven't yet checked if I have enough answers in the right tags to do all these steps myself)
