 where counts K ij for gene i, sample j are modeled using a Negative Binomial distribution with
 fitted mean µ ij and a gene-specific dispersion parameter α i . The fitted mean is composed of a
-sample-specific size factor s j and a parameter q ij proportional to the expected true concentration
-of fragments for sample j. The coefficients β i give the log2 fold changes for gene i for each col-
-umn of the model matrix X. The sample-specific size factors can be see as the logFC between condition.
