Talk:Mallows's Cp#Requested move 20 June 2025

My texts seem to use C_p, rather than Cp, except once in an index. Any objections to doing this in the text? I don't know how to treat the article title sensibly. Melcombe (talk) 13:15, 10 September 2008 (UTC)

Does Mallows' Cp can just be applied to compare nested linear regressions?

This article should be entitled “Mallows' Cp” rather than “Mallows's Cp”. — Preceding unsigned comment added by 109.154.36.38 (talk) 02:15, 31 August 2013 (UTC)

:Both are accepted styles, but the one used in this article, “Mallows’s”, agrees with the titles of the two references that have his name in the title. We have to do it the way the literature does. Loraof (talk) 17:48, 30 May 2018 (UTC)

{{requested move/dated|Mallows' 𝐶ₚ}}

:Mallows's Cp → {{no redirect|Mallows' 𝐶ₚ}} – (1) MOS:POSS is clear. (2) Mallows' is far more commonly used; a google search for Mallows's just redirects me. (3) I worked alongside Colin Mallows in the 1990's, and Mallows' is just the correct form to use; (4) The one reference currently in the article doesn't negate all this. (5) and the subscript p, italic C also should be fixed. Zaqrfv (talk) 23:17, 20 June 2025 (UTC)

• You said MOS:POSS is clear. Do you agree that it clearly says {{em|not}} to do what you're suggesting? —⁠ ⁠BarrelProof (talk) 02:19, 21 June 2025 (UTC)
• I also just noticed that the proposal is suggesting to use rather unusual character codes, which seems questionable under WP:TSC. My impression is that Wikipedia ordinarily handles italics and subscripting in a different way, e.g. using WP:DISPLAYTITLE, and this article is already doing that. —⁠ ⁠BarrelProof (talk) 05:52, 21 June 2025 (UTC)
• Moreover, the suggested title does not format the subscript in italic font. Is it asserted that using italics for the subscript is improper? (In any case, that is possible also with DISPLAYTITLE, but not using italics seems unconventional to me here.) —⁠ ⁠BarrelProof (talk) 18:33, 21 June 2025 (UTC)
• Oppose: Looking in Google Scholar at publications that discuss this, I'm seeing a lot of random variation about which form of possessive expression is used and whether each of the 'C' or 'p' are in italics, but I have the impression that the usual form is to use italics for both. Mallows himself seems to have put both the 'C' and the 'p' in italics, as shown [https://www.tandfonline.com/doi/abs/10.1080/00401706.2000.10485984 here]. DISPLAYTITLE is already being used appropriately, and the use of special character codes to accomplish italic formatting is not how Wikipedia ordinarily does things (and the suggested title would not have the 'p' in italics). The current article title seems to already be following MOS:POSS as well ("Mallows" is a singular noun, and this is similar to the {{tq|Descartes's philosophy}} example). —⁠ ⁠BarrelProof (talk) 18:46, 21 June 2025 (UTC)

If I understand correctly, the variable denoted as $P$ in the article should be $p$. Is that correct? It also appears to me that $K$ is not well explained, and should potentially be lowercase as well, for consistency with $p$. —⁠ ⁠BarrelProof (talk) 19:18, 21 June 2025 (UTC)
