Figure 4. The contributions to the ranking preservation of the HK, MR, and TS genes.

The three contributing factors were dispersion (solid line), stableness (dashed line), and co-expression (dotted line). For each factor, its contribution (in parenthesis) was the sum of the individual contributions calculated using tensor product decomposing equations, such as Equation (11 )–(13). The contribution of factors other than these three is given in the black box in the upper right corner of each panel.
