Gravity in meta-analysis

Gravity in meta-analysis (edit | talk | history | protect | delete | links | watch | logs | views) (delete) – (View log)

This article has only one external source, T. Gee, and questionable notability. It has been prodded by two editors, but both prods were recently removed. The article's creator Tgee1963 has been notified of the AFD. Plastikspork (talk) 15:03, 6 February 2009 (UTC)[reply]

  • Questions: (1) Is there some codified Wikipedia rule that says articles should have more than one external source? I think such a rule would be unwise; I can't see why it's grounds for deletion. (2) On what grounds do you regard this as being of questionable notability? You've merely made an assertion, here on this page. I find nothing in the article's discussion page on that point. Michael Hardy (talk) 15:07, 6 February 2009 (UTC)[reply]
    • Answers: (1) Yes. It's WP:N. Note that it says articles should have more than one external source, but not that articles need to have more than one reliable source. (2) I understand that but the question is who has the burden of proof: the person who says it isn't notable, or the person who says it is? Again there's Wikipedia policy on that, which is WP:BURDEN. That policy says unreferenced material should be cut, so the burden of proof is on the person who says it is notable to provide verifiable references from reliable sources to prove their case.--S Marshall Talk/Cont 15:21, 6 February 2009 (UTC)[reply]

*Merge with gravitation. I don't think there's enough here to warrant a separate article.--S Marshall Talk/Cont 15:23, 6 February 2009 (UTC)[reply]

  • Comment If I read the dif's correctly, the PROD's were removed by an established editor for whom I have a lot of respect. He also is rewriting this to make sense out of it. If it read as it does now, I'd have understood better what the article was about and not PRODed. Cheers, Dlohcierekim 15:27, 6 February 2009 (UTC)[reply]
  • Weak delete Keep. I originally added a Prod2 after having been unable to find any Gsholar hits, I think I used Gravity and "social science" as search terms. Repeating the search with "Gravity in Meta-Analysis" returns more hits. Closer examination reveals that there exists a so-called "gravity equation" in trade theory, see here p2 absolutely unrelated to meta-studies, but the trade theory papers incidentally also carry out meta-analysis. I concluded that I cannot find evidence of general accepted use of this concept. Another paper could be a hit here, I dont have full text access. One paper has been published on the topic, which is inherently noteworthy. I would like to see at least two papers to support that other than the author use this concept. Just because I could not find anything in the about 15 minutes I spent on this, is of course no proof that it does not exist. Unless more sources appear I would say delete.

  • keep per the expert ministrations of Melcombe. This is no longer the same article as the one I tagged for PROD. (It is no longer an OR-esque essay.) More sources would be preferable. And it should be moved to Gravity (meta-analysis), not merged. Cheers, Dlohcierekim 15:39, 6 February 2009 (UTC)[reply]
Change to delete persuaded by delete arguments. Dlohcierekim 14:01, 7 February 2009 (UTC)[reply]
  • Keep I note that a Google Scholar search now yields 1 journal-published article and 1 online paper referencing the original article, with none of the authors including the original author, which I think is quite good for only a few years. But the suggested move would be good. Melcombe (talk) 15:42, 6 February 2009 (UTC)[reply]
Could you be more specific, references please. Power.corrupts (talk) 15:45, 6 February 2009 (UTC)[reply]
Yes - Lukacik, Marek, Thomas, Ronald L., Aranda, Jacob V. A Meta-analysis of the Effects of Oral Zinc in the Treatment of Acute and Persistent Diarrhea Pediatrics 2008 121: 326-336 possibly at [1] and [2] Melcombe (talk) 15:48, 6 February 2009 (UTC)[reply]
Not convinced. The "Hospitals without Doctors" (here only refers to to Gee's paper, I cannot see that the paper seeks to apply or even discuss some sort of "outlier pruning" of studies. I'm really not sure that the paper is peer-reviewed, could be self-published (?). My library does not have online access to the other article (PEDIATRICS Vol. 121 No. 2 February 2008, pp. 326-336 (doi:10.1542/peds.2007-0921), I'm with a tech institution. Power.corrupts (talk) 16:02, 6 February 2009 (UTC)[reply]
Yes that paper (which might be something in preparation?) only includes Gee in the "Bibliography" without mentioning it. Strange that you can't see the Pediatrics article online as I can, and I'm not with anything medical or similar. I think I am allowed to quote a short part where Gee is mentioned ... "Another more recent approach proposed jackknife resampling to measure a concept termed “gravity.” In any meta-analysis, <snip> Gee proposed that jackknife resampling could be used to examine study influence and detect outlier studies. " ... and this is followed by a short summary, much as in the article here. Also, the paper does report some calculated values of "gravity", so it does seem to be actually being used.

Comment: I agree, the single reference appears to have a very weak citation count. The number of citations is a standard method of measuring notability. The weight to place on each measure is, coincidentally, a subject in meta-analysis. I would think that an article on statistics would aspire to have more than one source. Plastikspork (talk) 16:36, 6 February 2009 (UTC)[reply]
Delete. The term "gravity" in this context is a neologism proposed by Gee. From our guideline "To support ... an article about a particular term we must cite reliable secondary sources such as books and papers about the term". From my searching, I found only Gee's article as a source. This is only a single reference proposed by a single person. The reference was written in 2005. There does not appear to have been any widespread uptake of this term amongst the "statistics community". Axl ¤ [Talk] 18:38, 6 February 2009 (UTC)[reply]
It may need asking, but we can't ask it. The thing to establish is whether this concept is notable. The article's lack of sources suggest otherwise. Ddawkins73 (talk) 19:46, 9 February 2009 (UTC)[reply]
