Differential Expression Analysis for Pathways
Figure 5
Power curve, variable gene variance.
Performance of GSEA, SPIA, and DEAP are compared as gene variance (σ2g) changes. Power (y-axis) is the ratio of simulations, out of 5000 (5 pathways, 1000 simulations each), which were identified as significant (p<0.05). Constants were μ = 0.5 and sample size = 10.
