WebNov 22, 2024 · The wSS method calculates the sum of the weighted gene-wise statistic values over the set of genes (∑ j = 1 k w j r (D) j). Alternatively, a statistical probability hypergeometric model was applied. In the hypergeometric test, we used a cutoff p-value of 0.05 to define significant genes using their gene-wise statistics (i.e., p-values). WebThe default method for computing these scale factors uses a trimmed mean of M-values (TMM) between each pair of samples. We call the product of the original library size and the scaling factor the effective library size. The effective library size replaces the original library size in all downsteam analyses. d <- calcNormFactors(d) d
