Marginalization gaussian distributions
Webhas marginals that are uniformly distributed on the interval [0, 1]. The copula of is defined as the joint cumulative distribution function of : The copula C contains all information on the dependence structure between the components of whereas the marginal cumulative distribution functions contain all information on the marginal distributions of . WebWe discuss the two major parameterizations of the multivariate Gaussian—the moment parameterization and the canonical parameterization, and we show how the basic …
