The details for most of the mathematical tools implemented by CoDaImpact are developed in the article “Pairwise share-ratio interpretations of compositional regression models” by Dargel and Thomas-Agnan (2024). All numerical results can be reproduced following the instructions on the articles dedicated GitHub repository.
The article is accompanied by a vignette that provides additional illustrations for using CoDaImpact based on a case study of electoral sociology that analyses the 2022 French presidential elections. This vignette can be downloaded here.
