function corr(..) used in definition is not defined, and there is no (at least i cannot find any) link to its definition in wikipedia.

ie. it reads: >>> For random variables X(s) and X(t) at different points s and t of some space, the correlation function is

  C(s,t) = corr(X(s),X(t))

<<< but no explanation/link/definition of what "corr" is.

this is very important! it makes this page useless. --- I second the above comment, the definition given makes no sense. This page is useless. —Preceding unsigned comment added by 18.95.7.3 (talk) 23:14, 29 November 2008 (UTC)[reply]

I have added wikilink to article which now has definition of this notation. Melcombe (talk) 12:14, 2 December 2008 (UTC)[reply]

What then is the point of having an article titled "correlation function" which just points to another article for the definition of the correlation function? — Preceding unsigned comment added by 132.3.33.68 (talk) 19:06, 14 August 2012 (UTC)[reply]

Merger proposal

I am against merging in any of the other speciality-specific articles on correlation functions. Each speciality has its own conventions of terminology and don't necessarily agree on what the term "correlation function" means. Lets avoid confusion by keeping these different fields of application separate.Melcombe (talk) 16:45, 25 June 2008 (UTC)[reply]

I agree and have removed the merger template. However a merger with covariance function is worth considering. Skbkekas (talk) 03:56, 3 June 2009 (UTC)[reply]

Idea introduced by G.I Taylor

According to the historical notes in Fluid Mechanics (Kundu,Cohen), G.I Taylor introduced the idea of correlation function during a study of turbulent diffusion. Can anyone verify this and perhaps add this in the article ? —Preceding unsigned comment added by 193.157.204.95 (talk) 12:40, 27 March 2011 (UTC)[reply]
