Try this · assumptions · source

Try. Inspect the fixed marginal distributions, change the Gaussian dependence parameter and sample size, then compare the scatter and tail summaries.

Limits. Synthetic draws and a Gaussian copula. Its parameter is not generally the Pearson correlation of the displayed delays; extreme-tail dependence is not represented.
