This manuscript addresses the effect that the taxonomic bias inherent in microbiome measurement has on microbial differential-abundance analysis. We describe the basic problem posed by taxonomic bias for measuring changes in the abundance of particular taxa across conditions and describe new strategies for mitigating the errors it induces. Analyses of both relative and absolute abundances are considered. The manuscript is licensed under a CC BY 4.0 License. See the Zenodo record for how to cite the latest version.
