Talk:Regression analysis

this may well be an issue with the field of statistics in general and not necessarily one specific to Wikipedia but here it goes.

I found circular confusion by navigating across hyperlinks on this article and related ones, which I think should be rectified. under "General linear regression" a definition is given, which I rather think should be the one of "multiple linear regression". indeed, if one follows the link to the in-depth article on linear regression, this is how "multiple linear regression" is defined, with the added remark that this term is distinct from multivariate linear regression following which one in fact lands on the general linear model article.

I would vote for changing that "General linear regression" paragraph title to "Multiple linear regression".

Multiple regression analysis[edit]

I am surprised that the term "multiple regression analysis" is not in this article, and that there is not a clear distinction between this form of analysis and univariate regression analysis. Vorbee (talk) 10:49, 14 October 2017 (UTC)

Merger proposal[edit]

I propose that Curve fitting be merged into Regression analysis. The content in the "Curve fitting" article is largely redundant with that in "Regression analysis" and its linked pages, and merging any unique content it may contain into "Regression" will not cause any problems as far as article size or undue weight is concerned. "Curve fitting" is used colloquially in place of "regression analysis" to describe the same procedure, which suggests to me that a redirect would be appropriate. Regression analysis would benefit from at least a brief comment on the common use of the term "curve fitting", noting this equivalence, since the term "regression" is opaque, and can be confusing. Regression analysis#History might be a good place to do this, since it does talk about how "regression" is historical jargon (originally describing how a curve was fit to a set of points which just so happened to represented heights that 'regressed' the the population mean). Leaving the articles as they are tends to promote a false distinction. aaron0h (talk) 17:45, 19 January 2018 (UTC)

  • Oppose. The two topics have overlap, but they are distinct. Regression implies a statistical fit. Curve fitting can include cases of an exact fit. See lead paragraph of Curve fitting. Glrx (talk) 19:29, 16 February 2018 (UTC)
  • Oppose. Most of the article Curve fitting is about things other than regression. Loraof (talk) 16:50, 5 May 2018 (UTC)
