Fig 8. Correlation of Sectors’ Normalised Strength.

Left: Correlated sectors - sectors are connected with a dark grey link if the Pearson coefficient between their strengths time series is above $T_1^{+}=0.91$ if the coefficient is only above $T_0^{+}=0.82$ the link is light grey. Right: Anticorrelated sectors - Two sectors are connected in dark grey if their strengths time series have a Pearson coefficient below $T_1^{-}=-0.89$ if the coefficient is only below $T_0^{-}=-0.80$ the link is light grey. In both the size of of the nodes is proportional to the strength of the node (regarding light edges).
