Correlation function Guide, Meaning , Facts, Information and Description
In statistics and probability, in particular in stochastic processes, the value of a correlation function r(s,t) is the correlation between random variables Xs and Xt, where the indices s and t are often either points in time or physical locations.A caveat, though, in quantum field theory, we sometimes have nonpositive states and in that case, a probabilistic interpretation makes no sense. At any rate, even in ordinary quantum field theory, we need to work with quantum probability instead of classical probability.
