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]

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]
