Figure 2. — Probability density functions of the statistic ρ_xy⁽^k⁾ when (A) genes x and y are independent of each other; (B) genes x and y are dependent in partial cells; (C) genes x and y are dependent in all cells. Red plots in the scatter diagrams of genes x and y represent that the statistic ρ_xy⁽^k⁾ in these plots is larger than the significant level of 0.01 and edge_xy⁽^k⁾ = 1, which corresponds to the red area in the density function graphs. Blue plots represent that ρ_xy⁽^k⁾ in these plots is smaller than the significant level of 0.01 and edge_xy⁽^k⁾ = 0, which corresponds to the blue lines in the density function graphs. Sample size n = 500, and n_x⁽^k⁾ = n_y⁽^k⁾ = 0.1n.
