Statistical Methods for Detecting Differentially Abundant Features in Clinical Metagenomic Samples

Figure 3

Dispersion estimates (φ) for three metagenomic datasets used in this study.

These plots compare dispersion values between (A) obese and lean human gut taxonomic data, (B) infant and mature human gut COG assignments, and (C) microbial and viral subsystem annotations. We find a wide range of possible dispersions in this data and significant differences in dispersions between two populations.
