Comparison of the statistical power. The proposed method (solid black) results in a substantial increase in power of detecting homology groups that were differentially expressed in multiple species compared to other methods (average - dotted blue, random - mixed green and combined - dashed red). The x-axis shows the size of the differential expression and the y-axis the corresponding power. See Methods for full details about the simulation.
