From: Inherent directionality explains the lack of feedback loops in empirical networks
Correlation between inferred and explicitly measured levels of directionality.
Scatter plot of the optimal values of the directionality parameter γ plotted against the current parameter χ. Values of either γ or χ close to 1 reflect a high degree of directionality while smaller values close to 1/2 imply that link directions are nearly uncorrelated with directionality. The value of the linear correlation coefficient is r = 0.89 or r = 0.92 depending on whether the outlier “Coachella Valley” small network is included or not. The corresponding best fits are γ = 0.487χ + 0.529 and γ = 0.514χ + 0.502, respectively.
