The determinacy index SI versus SNR for various time series under different levels of added Gaussian white noise (left panels) and colored noise (right panels). These series correspond to the (a) Lorenz, (b) Rossler, (c) Van der Pol, (d) Mackey-Glass, and (e) high dimensional time series. Horizontal dashed lines in each panel denote the critical SI values of 0.3 and 0.7 for detecting determinacy.
The determinacy index SI versus SNR for the ecological map time series under various levels of added Gaussian white noise (left panel) and colored noise (right panel). Horizontal dashed lines in both panels denote the critical SI values of 0.3 and 0.7 for detecting determinacy.
Typical raw MMG signal recorded at the biceps from subject 2 (a) and (b) its surrogate series.
Attractor for the MMG signal, obtained by phase reconstruction of typical raw MMG data.
Second-order difference plots of the angle series from successive tangent vectors of the trajectory in (a) MMG data in subject 3 and (b) its surrogate data.
The distribution of the values of ctm obtained for the 39 surrogates of the MMG signal in subject 5. The ctm value of the original signal is represented by a red hexagram.
The determinacy index SI for MMG signals obtained by SPCA-CTM and CTM methods in five human subjects.
