WebFeb 22, 2024 · Details. Typically the function is called with the idiom: dds <- estimateDispersions(dds) The fitting proceeds as follows: for each gene, an estimate of the dispersion is found which maximizes the Cox Reid-adjusted profile likelihood (the methods of Cox Reid-adjusted profile likelihood maximization for estimation of dispersion in RNA …
