Fig. 7From: Theoretical study of the effect of ports in the formation of city systemsPort configurations. Dynamics of the statistical distributions, skewness, and correlations. The skewness was computed by the Fisher-Pearson coefficient scipy.stats.skew. Each value of skewness is associated with each curve of statistical distribution per case. Scatter plots: (x-axis = Manhattan distance to closer port, y-axis = city-size)Back to article page
