It can be computed using the trick of combining two one-dimensional Gaussians. Here, use has been made of the fact that the variable in the integral is a dummy variable that is ...
WebIn probability theory and statistics, a copula is a multivariate cumulative distribution function for which the marginal probability distribution of each variable is uniform on the interval [0, 1]. Copulas are used to describe/model the dependence (inter-correlation) between random variables. Their name, introduced by applied mathematician Abe Sklar in 1959, comes …
