Confounding Effects of Phase Delays on Causality Estimation

Figure 6

Scenario 3: time series and spectral power.

Characteristics of the driver and response in the case of a positive phase difference () at Hz (see Fig. 5): (A) simulated signals (two seconds of a randomly chosen realization); and (B) mean spectral density and cross power spectral density, averaged across realizations. The errorbars represent the standard error computed across realizations.
