Casting doubt on the example gene identified as DE using RMA/limma. multi-mgMOS expression levels for the gene determined by RMA/limma to be most likely to be differentially expressed due to the interaction term in the estrogen data set. Note that multi-mgMOS provides error bars as well as point estimates for the expression levels.
