WebedgeR normalizes by total count. edgeR is concerned with differential expression analysis rather than with the quantification of expression levels. It is concerned with relative changes in expression levels between conditions, but not … WebJun 13, 2024 · edgeR uses the negative binomial (NB) distribution to model the read counts for each gene in each sample. The dispersion parameter of the NB distribution accounts for variability between biological replicates (McCarthy, Chen, and Smyth 2012). edgeR estimates an empirical Bayes moderated dispersion for each individual gene. It …
