The dccpp R Package

R-CMD-check GitHub Workflow Status (branch) Lifecycle: stable

Fast computation of the distance covariance dcov and distance correlation dcor. The computation cost is only O(n log(n)) for the distance correlation (see Chaudhuri, Hu, 2019, arXiv, elsevier). The functions are written entirely in C++ to speed up the computation.

Installation

Install from CRAN

install.packages("dccpp")

Install from GitHub

# install.packages("remotes")
remotes::install_github("BerriJ/dccpp")

Usage

dcov(x, y) # To calculate the distance covariance
dcor(x, y) # To calculate the distance correlation
