Provides functions for density evaluation and both joint and conditional random sampling from a Gaussian Copula distribution with arbitrary margins. This is achieved by storing univariate marginal distributions as extended density (xDensity) objects which provide d/p/q/r methods, and which can be estimated from data using a variety of parametric, nonparametric, and semiparametric approaches.
An overview of the GaussCop::xDensity class and other package utilities is provided in the package vignette.
