WebIt is also possible to analyse DGE data using a common dispersion for each tag using edgeR. 6 Estimating dispersions 6.1 Two ways of estimating dispersions When a … Webdispersion numeric scalar or vector of dispersions. y numeric matrix of counts. design numeric matrix giving the design matrix. offset numeric matrix of same size as y giving offsets for the log-linear models. Can also be a scalar (i.e., a single value) or a vector of length ncol(y), in which case it is expanded out to a matrix.

Differential Expression Analysis using edgeR (Exact-Test)

WebTypical BVC for genetically identical model organisms is 0.1, so you should set the dispersion guess at 0.01 for this kind of data. Once negative binomial models are fitted and dispersion estimates are obtained, edgeR proceeds with testing for differential expression using the exact test, which is based on the qCML methods. Output WebestimateTagwiseDisp.DGEList adds the following components to the input DGEList object: prior.df. prior degrees of freedom. prior.n. estimate of the prior weight. tagwise.dispersion. numeric vector of the tagwise dispersion estimates. span. width of the smoothing window, in terms of proportion of the data set.
