WebNov 27, 2024 · lrt <- glmLRT(fit, coef = 2:4) compares everything to everything, because you only have 4 time-points and hence only 3 df for comparisons. Your code immediately overwrites the above with lrt <- glmLRT(fit) so you haven't stored the above result anyway. glmLRT(fit) tests something different, as I now explain in my answer above. ... WebglmLRT conducts likelihood ratio tests for one or more coefficients in the linear model. If coef is used, the null hypothesis is that all the coefficients indicated by coef are equal …

WebDetails. glmFit and glmLRT implement generalized linear model (glm) methods developed by McCarthy et al (2012).. glmFit fits genewise negative binomial glms, all with the same design matrix but possibly different dispersions, offsets and weights. When the design matrix defines a one-way layout, or can be re-parametrized to a one-way layout, the glms are …
WebJan 21, 2013 · #2 12-11-2012, 07:47 AM You should filter according to the FDR value and not the raw p-value, that's why you are seeing more differentially expressed genes using your own function compared to the built-in in edgeR. bunny and her boys spoilersWebDear edgeR patrons, I am using edgeR to find genes differentially expressed between infected and mock-infected control plants, at 3 time points after infection. I have RNAseq data for 3 independent tests, so for every single test I have 6 libraries (control + infected at 3 time points). Having three replicates this makes 18 libraries in total. bunny and fox mixWebRNAseq pipeline.
