However, because of the compositional constraint and the prevalence of zero counts in the data, differential abundance analysis on compositional data remains a complicated and unsolved statistical problem. This article proposes a new differential abundance test, the robust differential abundance test, to address these challenges. Compared with existing methods, the robust differential abundance test is simple and computationally efficient, is robust to prevalent zero counts in compositional datasets, can take the data\u2019s compositional nature into account, and has a theoretical guarantee of controlling false discoveries in a general setting. Furthermore, in the presence of observed covariates, the robust differential abundance test can work with covariate-balancing techniques to remove potential confounding effects and draw reliable conclusions. The proposed test is applied to several numerical examples, and its merits are demonstrated using both simulated and real datasets.<\/jats:p>","DOI":"10.1093\/biomet\/asac029","type":"journal-article","created":{"date-parts":[[2022,5,23]],"date-time":"2022-05-23T12:37:13Z","timestamp":1653309433000},"page":"169-185","source":"Crossref","is-referenced-by-count":12,"title":["Robust differential abundance test in compositional data"],"prefix":"10.1093","volume":"110","author":[{"given":"Shulei","family":"Wang","sequence":"first","affiliation":[{"name":"University of Illinois at Urbana-Champaign Department of Statistics, , 605 E.
