  1. Rankings from best to worst (1 to 5) of average pAUC scores (using a threshold of 0.05) of the six tests of differential expression. The average pAUC for each score is in parentheses. The LMGene package was used to apply the Loess normalization and glog transformation to the cDNA data. BC indicates that background correction was applied to the data before normalization.
