WebBy using the preceding construction we can form the joint distribution H with a Gaussian copula and marginals F and G. To depict this distribution, here is a partial plot of its bivariate density on x and y axes: The dark areas have low probability density; the light regions have the highest density. A bivariate Gaussian probability density function centered at (0, 0), with covariance matrix given by Sample points from a bivariate Gaussian distribution with a standard deviation of 3 in roughly the lower left–upper right direction and of 1 in the orthogonal direction.
