Sample from copula: a COPPY module

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 \textsf{R} software, methods to work with copula in \textsf{Python} are still in their infancy. To promote the dependence modeling with copula in \textsf{Python}, we have developed \textbf{COPPY}, a library that provides a range of random vector generation vector for copulae.
