The reason not to subtract off 3 is that the bare fourth moment better generalizes to multivariate distributions, especially when independence is not assumed.

The learning of PGMs encoding multivariate distributions is a computationally expensive task, therefore, it is usual for EDAs to estimate multivariate statistics from bivariate statistics.
13.
The point of Gibbs sampling is that given a multivariate distribution it is simpler to sample from a conditional distribution than to marginalize by integrating over a joint distribution.
14.
In statistical theory, one long-established approach to higher-order statistics, for univariate and multivariate distributions is through the use of cumulants and joint cumulants.
15.
For multivariate distributions, formulae similar to those above apply with the symbols " X " and / or " Y " being interpreted as vectors.
16.
Bivariate and multivariate distributions are usually represented as Probabilistic Graphical Models ( graphs ), in which edges denote statistical dependencies ( or conditional probabilities ) and vertices denote variables.
17.
The underlying random variables may be random real numbers, or they may be random vectors ( each having the same dimension ), in which case the mixture distribution is a multivariate distribution.

The reason I'm looking for multivariate distributions, is that I'm investigating the possibility of a thesis subject on machine learning in this general area, which means multivariate distributions.

The Wikipedia entry for copulas ( http : / / en . wikipedia . org / wiki / Copula _ % 28probability _ theory % 29 # Empirical _ copulas ) lists a procedure for generating random samples from a multivariate distribution.
