Introduction¶
The Bayesian Quantile Regression (BQReg) library is a lightweight C++ implementation of Bayesian quantile regression using the asymmetric Laplace density representation of the problem, with bindings for Python and R.
Features:
A header-only C++11 library with OpenMP-accelerated MCMC sampling for parallel computation.
Built on the Eigen (version >= 3.4.0) templated linear algebra library for fast and efficient matrix-based computation.
Straightforward linking with parallelized BLAS libraries, such as OpenBLAS.
Seamless integration with Python and R through Pybind11 and Rcpp modules.
Available as a single precision (
float
) or double precision (double
) library.Released under a permissive, non-GPL license.

Installation¶
The C++ implementation of BQReg is a header-only library. First, clone the library and related submodules:
# clone optim into the current directory
git clone https://github.com/kthohr/BayesianQuantileRegression ./BayesianQuantileRegression
# change directory
cd ./BayesianQuantileRegression
# clone necessary submodules
git submodule update --init
Then simply add the BQReg header files (found under cpp/include
) to your project using:
#include "bqreg.hpp"
Beyond the files contained in the Git submodules, the only dependencies are a copy of Eigen (version >= 3.4.0) and a C++14-compatible compiler.
For detailed instructions on how to install the R and Python bindings, see the installation page.
