Overview

About

Maintained by Marieke StolteFirst published 2025-03-184 releasesCRAN page ↗

A collection of methods for quantifying the similarity of two or more datasets, many of which can be used for two- or k-sample testing. It provides newly implemented methods as well as wrapper functions for existing methods that enable calling many different methods in a unified framework. The methods were selected from the review and comparison of Stolte et al. (2024) doi:10.1214/24-SS149. An empirical comparison of the methods was performed in Stolte et al. (2026) doi:10.48550/arXiv.2604.11458 for categorical data and in Stolte et al. (2026) doi:10.48550/arXiv.2604.12327 for numeric data.

Install

R (CRAN)Ubuntu (r2u)openSUSE (OBS)

install.packages("DataSimilarity", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-datasimilarity

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-DataSimilarity

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
