PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

fisher's exact test for differential expression analysis

Ann Loraine   (2009-05-28 14:14)  UNC Charlotte email

I'm curious about the authors' use of Fisher's exact test of contingency tables for the short-reads differential expression testing. It's an easy test to perform and it would be great if it's appropriate to use in this setting. But I think the contingency tables, if I understand the approach, will have vastly different numbers in the cells of the table. How does the test perform under these conditions? I would welcome some additional discussion of this issue.
