Correlation functions are calculated from histograms of probability densities. This method allows to analyse correlations of higher moments from the data. At least for exploratory studies it is by far more practical than direct calculation of the correlations of higher moments during the simulation.

β¦ Synopsis
Given a population and a random vector X, by using distances between observations of X, we prove that it is, in general, possible to construct probability densities for X. This distance-based approach can present problems, from a multidimensional scaling point of view, for some monotonic density functions, where the construction must be made on the basis of symmetric functions instead of distances. A measure of divergence between the true density and this construction is given. The procedure aims to offer alternative methods for performing discriminant analysis.
