Sampling from copulae

## Sampling from copulae

The modeling of dependence between random variables is an important subject in several applied fields of science. To this aim the copula function can be used as a margin-free description of the dependence structure. Several copulae belong to specific families such as Archimedean, Elliptical or Extreme. While software implementation of copulae has been thoroughly explored in R software, methods to work with copula in Python are still in their infancy. To promote the dependence modeling with copula in Python, we have developed clayton, a library that provides a range of random vector generation vector for copulae.

The module clayton is implemented using the object-oriented features of the Python language. The classes are designed for Archimedean, elliptical, extreme value copulae. Each contains methods to generate random vectors.
