![An introduction to simulating correlated data by using copulas](https://blogs.sas.com/content/iml/files/2021/07/copula3-500x336.png)
Do you know what a copula is? It is a popular way to simulate multivariate correlated data. The literature for copulas is mathematically formidable, but this article provides an intuitive introduction to copulas by describing the geometry of the transformations that are involved in the simulation process. Although there are
