Venn Diagrams May Indicate Erroneous Statistical Reasoning in Transcriptomics [PDF]
A common application of differential expression analysis is finding genes that are differentially expressed upon treatment in only one out of several groups of samples. One of the approaches is to test for significant difference in expression between treatment and control separately in the two groups, and then select genes that show statistical ...
