Should the page [[cumulative density function]] be:
* Option '''A''': a redirect to [[cumulative distribution function]]
Line 105 ⟶ 104:
*:Could you explain the significance of WP:2DABS here? —[[User:St.nerol|St.Nerol]] ([[User talk:St.nerol|talk]], [[Special:Contributions/St.nerol|contribs]]) 22:01, 22 April 2025 (UTC)
*::If there are only two topics to disambiguate and one of them is primary, we should not have a disambiguation page (so we should not do option B); instead, we should have a redirect to the primary topic and a hatnote on that article pointing to the other one. —[[User:David Eppstein|David Eppstein]] ([[User talk:David Eppstein|talk]]) 23:12, 22 April 2025 (UTC)
*:::Thanks! For further clarification, would the hatnote be permanently visible at the top of [[cumulative distribution function]]? If so, given that most readers would not arrive there from this page, how could such a note be phrased? —[[User:St.nerol|St.Nerol]] ([[User talk:St.nerol|talk]], [[Special:Contributions/St.nerol|contribs]]) 22:33, 23 April 2025 (UTC)
*::::If there were one, then yes it would be; this is fairly standard. Search for uses of {{tl|redirect}} to see examples. I personally would somewhat prefer that we not have such a hatnote (see my response to Elemimele) but in any case I think that's a little outside the scope of this RFC, which is about what to do with ''this'' page. --[[User:Trovatore|Trovatore]] ([[User talk:Trovatore|talk]]) 23:17, 23 April 2025 (UTC)
*Option '''A'''. It's a fairly innocuous back-formation from CDF by analogy with PDF. We should give the reader what they are looking for and not a lecture on proper terminology. —[[User:St.nerol|St.Nerol]] ([[User talk:St.nerol|talk]], [[Special:Contributions/St.nerol|contribs]]) 22:07, 22 April 2025 (UTC)
*Option '''A'''. (invited here by the RfC bot) Being cumulative, it isn't a PDF, so we don't need to clarify that.---'''[[User:Avatar317|<span style="background:#8A2BE2; color:white; padding:2px;">Avatar317</span>]][[User talk:Avatar317|<sup><span style="background:#7B68EE; color:white; padding:2px;">(talk)</span></sup>]]''' 23:07, 22 April 2025 (UTC)
*{{sbb}} Option '''A''' and hatnote to option B per David's comments above.

* '''Hatnote''' at Cumulative distribution function pointing to probability density function, and option '''A'''. The current (helpful!) disambig doesn't lecture the reader; the only complaint that can be levelled against it is that it falls foul of [[WP:2DABS]], and the 2DABS argument is that if there are only two targets, they ''should'' be dealt with by hat-notes instead, so merely redirecting without a hat-note is a very poor choice. Most readers may be looking for CDF, but we shouldn't make personal assumptions or ignore the minority who were aiming for PDF.

**'''Comment''' Such a hatnote wouldn't be the worst thing in the world, but I really don't see the need for it. I doubt this is a common error. It's just not particularly plausible that someone would type "cumulative" when thinking of the PDF. --[[User:Trovatore|Trovatore]] ([[User talk:Trovatore|talk]]) 20:40, 23 April 2025 (UTC)
*'''Comment''' Is there any evidence that "cumulative density function" has ever meant anything else than "cumulative distribution function", anywhere? —[[User:St.nerol|St.Nerol]] ([[User talk:St.nerol|talk]], [[Special:Contributions/St.nerol|contribs]]) 20:25, 24 April 2025 (UTC)
* Option '''A''': Someone looking for a "cumulative density function" is clearly looking for something cumulative, or they wouldn't have included an extra word to express that. No hatnote seems necessary to me; it seems like just a misnomer but not really unclear. (It also doesn't seem common, so not worth the clutter.) —⁠ ⁠[[User:BarrelProof|BarrelProof]] ([[User talk:BarrelProof|talk]]) 17:07, 29 April 2025 (UTC)
* David Eppstein wrote: "If there are only two topics to disambiguate and one of them is primary" etc. I don't think that rule was intended for cases where the title of the article is a complete misnomer and oxymoron, like "cumulative density function." [[User:Michael Hardy|Michael Hardy]] ([[User talk:Michael Hardy|talk]]) 05:28, 6 May 2025 (UTC)
** '''Comment''' it is not clear to me that it is a complete misnomer and oxymoron. I agree that it's a poorer choice of terminology than "cumulative distribution function", but as I said above, I do not agree with calling it an error in Wikivoice, unless reliable secondary sources specifically making that exact claim can be found. --[[User:Trovatore|Trovatore]] ([[User talk:Trovatore|talk]]) 05:41, 6 May 2025 (UTC)
 
===Discussion===
* '''Procedural comment'''. I believe I have notified everyone who participated in either the discussion above or the AfD, but if I missed anyone, please let me know. --[[User:Trovatore|Trovatore]] ([[User talk:Trovatore|talk]]) 21:38, 22 April 2025 (UTC)
*:Thank you @[[User:Trovatore|Trovatore]] for the notification. I have not followed the discussion, and two years have passed since the AfD. If the consensus here renders that moot, feel free to take whatever action consensus determines now.

Since a couple of editors talk about adding a hatnote at [[cumulative distribution function]], I'll make a note at that talk page. —[[User:St.nerol|St.Nerol]] ([[User talk:St.nerol|talk]], [[Special:Contributions/St.nerol|contribs]]) 16:47, 1 May 2025 (UTC)
