Attention needed[edit]
I think this material at least needs reordering so as to start with the regression-related stuff. It seems incorrect to say at the start of the definition "Explained variation is a relatively recent concept" when it has been used in regression for a long time - it may be that this phrase was meant to refer to the specific "information theory" bit that follows, in which case some rephrasing is needed.

Removal of sourced material[edit]
See this: [1] Please explain. Here is the source: [2] Miradre (talk) 15:04, 8 July 2011 (UTC)
- Yes. The content in the article does not match the source. aprock (talk) 15:05, 8 July 2011 (UTC)
- It does. I quote: "The nature of most social scientific work, however, generates data poorly described by the first specification."Miradre (talk) 15:08, 8 July 2011 (UTC)
- The content you inserted does not match that quote. Incorrect != "poorly described by". Additionally, that source does not deal with the issue of social sciences, but is a rebuttal to a specific work of research. It's relevance to this article is only tangential. There is little reason to include it here. aprock (talk) 15:50, 8 July 2011 (UTC)
- It is certainly a criticism of the explained variance concept and as such is relevant. I will simplfy the criticism and reinsert it.Miradre (talk) 15:56, 8 July 2011 (UTC)
- The source is a criticism of a paper not a method. Inclusion here is undue. aprock (talk) 16:22, 8 July 2011 (UTC)
- The paper there are two situations regarding explained variance: 1. Unconditional regression. However, this does no apply for most social scientific work. 2. Conditional regression. This is not particularly good and the standard error of estimate should be used instead. So yes, the paper is a critique of using explained variance under many situations, particularly in social sciences. That it is a reply to another paper is not relevant. It a valid POV regarding explained variance.Miradre (talk) 16:29, 8 July 2011 (UTC)
- You haven't addressed the issue of WP:UNDUE in any way. Until you do, there is little to discuss. aprock (talk) 16:38, 8 July 2011 (UTC)
- It violates UNDUE regarding the argument for explained variance to not include sourced criticisms. Here is the full paper: {http://www.rochester.edu/College/PSC/clarke/405/Achen90.pdf]. To quote from the conclusion: ""Explained variance" explains nothing."Miradre (talk) 16:40, 8 July 2011 (UTC)
