Quantifying Similarity of Datasets and Multivariate Two- And k-Sample Testing

Description

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.

The package provides various methods for comparing two or more datasets or their underlying distributions. Often, a permutation or asymptotic test for the null hypothesis of equal distributions H_0: F_1 = F_2 or H_0: F_1 = \dots = F_k is performed.
