Temporal invariance of centrality correlations and hierarchical topology in evolving cross-shareholding networks in Japan (2001–2023)
Fig 9
Temporal changes in Kendall’s rank correlation coefficients between pairs of network measures in the SCCN.
The subfigures are shown in descending order based on the average Kendall’s rank correlation coefficient (τ) over time. Gray shading represents the consecutive time points at which the 95% bootstrap confidence interval of the difference in Kendall’s τ excluded zero, indicating statistical significance at the 5% level. For example, panel (a) shows the temporal variation in the correlation between sout and h.
