Using Relative Abundance Data to Estimate of Multiplicative Differences in Mean Absolute Abundance R package radEmu version 2.3.2.0 A differential abundance method for the analysis of microbiome data. 'radEmu' estimates fold-differences in the abundance of taxa across samples relative to "typical" fold-differences. Notably, it does not require pseudocounts, nor choosing a denominator taxon.
