Introduction

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 vine-copula.org.

What is pyvinecopulib?

pyvinecopulib is the python interface to vinecopulib, 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.

Installation

With pip

The latest release can be installed using pip:

bash pip install pyvinecopulib

With conda

Similarly, it can be installed with conda:

bash conda install conda-forge::pyvinecopulib

Or with mamba:

bash mamba install conda-forge::pyvinecopulib

From source

Start by cloning this repository, noting the --recursive option which is needed for the vinecopulib and wdm submodules:

bash git clone --recursive https://github.com/vinecopulib/pyvinecopulib.git cd pyvinecopulib

The main build time prerequisites are:

  • scikit-build-core (>=0.4.3),
  • nanobind (>=2.7.0),
  • a compiler with C++17 support.

To install from source, Eigen and Boost also need to be available, and CMake will try to find suitable versions automatically.

The recommended way to install pyvinecopulib from source is to use conda or mamba. A reproducible environment, also including requirements for the pyvinecopulib's development and documentation, can be created using:

bash python scripts/generate_requirements.py --format yml # from pyvinecopulib's root mamba env create -f environment.yml mamba activate pyvinecopulib

Alternatively, you can specify manually the location of Eigen and Boost using the environment variables EIGEN3_INCLUDE_DIR and Boost_INCLUDE_DIR respectively. On Linux, you can install the required packages and set the environment variables as follows:

bash sudo apt-get install libeigen3-dev libboost-all-dev export Boost_INCLUDE_DIR=/usr/include export EIGEN3_INCLUDE_DIR=/usr/include/eigen3

Finally, you can build and install pyvinecopulib using pip:

bash pip install .

Stubs can then be generated using:

bash PYTHONPATH=$(python -c "import site; print(site.getsitepackages()[0])") \ python -m nanobind.stubgen \ -m pyvinecopulib.pyvinecopulib_ext \ -o src/pyvinecopulib/__init__.pyi \ -M src/pyvinecopulib/py.typed

Note that the generate_requirements.py script can also be used to generate a requirements.txt file for use with pip via the --format option:

bash python scripts/generate_requirements.py --format txt

Building the documentation

Documentation for the example project is generated using Sphinx and the "Read the Docs" theme. The following command generates HTML-based reference documentation; for other formats please refer to the Sphinx manual:

bash cd docs python serve_sphinx.py
