Figure 4

Variation in steady state values for Models 1, 9, 12, and 14. Boxplots show the distributions of the 81 coefficients of variance for all three genes using seven different Hill coefficients ranging from p = 1 to p = 100. For each Hill coefficients the three plots show from left to right the coefficient of variation for gene 1 (red), 2 (green), and 3 (blue), respectively. The boxes show the quartiles and the median. The black vertical lines extend to the largest observation and the smallest. The long black horisontal line shows the coefficient of variation 0.288 of the perturbed production rates α _j .
