We have tens of questions mentioning Cook's distance. Should we have a tag for them?

    $\begingroup$ We already seem to have a tag for leverage (but not one for influence). Do we need to have separate ones for all of these concepts? This is a genuine question to which I have no answer. $\endgroup$ – mdewey Feb 20 '17 at 18:40
  • $\begingroup$ @mdewey What is "leverage" (the [leverage] tag has no wiki excerpt), and how is it related to Cook's distance? $\endgroup$ – amoeba Feb 20 '17 at 19:18

    $\begingroup$ @amoeba as in en.wikipedia.org/wiki/Leverage_(statistics). I view Cook as a compromise between leverage and residual in my simplistic way. If there is a consensus about these concepts I will write the wiki for leverage unless someone gets there first. $\endgroup$ – mdewey Feb 21 '17 at 8:49

At the moment we have a number of possibly relevant tags

  1. which has 27 entries but no wiki excerpt
  2. which has 162 entries a wiki excerpt but no extended wiki
  3. which is a synonym of
  4. which has 10 entries and no wiki excerpt

As @Pere remarks we have no tag for Cook's distance.

There are well used tags for and .

The simplest solution would be to create the tag for Cook's distance, write wikis for it and leverage and in them suggest the possibility of using if more than one diagnostic is being considered.

EDIT added 1 March 2017

We now have a tag with wiki and excerpt and also wiki and excerpt for . I will tag the ones picked up in the search noted in comments.

Further edit 6 March

I have now gone through all the ones thrown up by @Amoeba's search mentioned in comments and tagged most of them. Some, about one quarter, were not really about Cook, they just mentioned it so I have left them un-tagged.
