vinecopulib: a C++ library for vine copula modeling

What are vine copulas?

Vine copulas are a flexible class of dependence models consisting of bivariate building blocks (see e.g., Aas et al., 2009). You can find a comprehensive list of publications and other materials on

What is vinecopulib?

vinecopulib is a header-only C++ library for vine copula models based on Eigen. It provides high-performance implementations of the core features of the popular VineCopula R library, in particular inference algorithms for both vine copula and bivariate copula models. Advantages over VineCopula are

  • a stand-alone C++ library with interfaces to both R and Python,
  • a sleaker and more modern API,
  • shorter runtimes and lower memory consumption, especially in high dimensions,
  • nonparametric and multi-parameter families.


Version 0.6.0 was released on July 12, 2021. While we did our best to design a user-friendly API, the library is still under active development and changes are to be expected. We are also working on interfaces for R and Python.
