Dear all, I have a question regarding using SAM in R for discerning differentially expressed genes from microarray gene expression datasets. I have 4 treatments in total, and I plan to use the multiclass option. How does the multiclass work? (i.e. how does the algorithm under this setting decide if a gene is differentially expressed or not). I am unable to find a paragraph explaining this, other than the mathematical equation provided in SAM's documentation. Thanks a lot in advance!Sincerely,Cassie _________________________________________________________________ [[alternative HTML version deleted]]
