Evaluation of the first step of the ORdensity method using different values of α. The Table shows the estimated probability, , of no considering as a potential DE gene at least one gene that it really is, and the mean proportion of DE genes (row named “%”) that the procedure considered as potential DE genes. Corresponding standard deviations are in brackets
