Comparison of the performance of methods with synthetic data associated with varying levels of noise. Boxplots of the number of the true and false DE genes using the FCROS (fcros), FC (fc), WAD (wad), RP (rp), Student t-test (ttest), SAM (sam) and TREAT (treat) methods. The noise level parameter σ
was set to 0.2, 0.4 and 0.6. 100 simulations were used for these results.
