Clustering coefficient entropy <i>E</i>_<i>c</i> inferred from multivariate data versus scale factor <i>τ</i>.

<p>The multivariate time series consists of <i>Z</i>-components of four isolated time series. The average value of the normal group (green) is smaller than that of the patient group (red). The difference is statistically significant (student’s <i>t</i>-test, <i>p</i> < 0.05) in every examined scales (<i>τ</i> ≤ 15). Below <i>τ</i> = 5, every normal subject has a smaller value of <i>E</i>_<i>c</i> than every patient, as manifested by the small error bars.
