الوصف: | Motivation: P values derived from the null hypothesis significance testing framework are strongly affected by sample size, and are known to be irreproducible in underpowered studies, yet no suitable replacement has been proposed. Results: Here we present implementations of non-parametric standardized median effect size estimates, dNEF, for high-throughput sequencing datasets. Case studies are shown for transcriptome and tag-sequencing datasets. The dNEF measure is shown to be more reproducible and robust than P values and requires sample sizes as small as 3 to reproducibly identify differentially abundant features.

Comment: Draft paper explaining the properties and utility of the ALDEx2 effect size metric |
