DENBStat4GSEA:
Calculate NB-statistics quantifying differential expression for each gene
Description
Calculate NB-statistics quantifying differential expression between two groups of samples compared.
The results will be used for GSEA run. Comparing with DENBTest, this function will not
calculate NB test p-values.
This function only works with two-group comparison.
Usage
DENBStat4GSEA(cds)
Arguments
cds
A CountDataSet object with size factors and dispersion parameters estimated. Recommended to take the output of runDESeq.
Value
A data frame containing each gene's expression means and variances in each group, and each gene's DE NB-statistics.
