We have tens of questions mentioning Cook's distance. Should we have a tag for them?
At the moment we have a number of possibly relevant tags
- leverage which has 27 entries but no wiki excerpt
- diagnostic which has 162 entries a wiki excerpt but no extended wiki
- regression-diagnostic which is a synonym of diagnostic
- schoenfeld-residuals which has 10 entries and no wiki excerpt
As @Pere remarks we have no tag for Cook's distance.
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 diagnostic if more than one diagnostic is being considered.

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.
