hypothesis simulations with 20% of the genes differentially expressed and correlated with the same correlation coefficient and
80% of the genes non-differentially expressed and uncorrelated. For = 700 , the 700 = 7x100 simulated data sets per
plot were obtained by independently generating 100 data sets for each of seven different values of the population mean
differential expression Δ . These seven values of Δ = Δ(1– ) were obtained such that the corresponding power of the
ordinary t-test in detecting the differentially expressed genes was varied by1– = 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 . For
= 2000 the 30 simulated data sets correspond to 1– = 0.5 only. The situation = 2000 is simulated for
= 4, 6 but not for =1
