Instantaneous Granger Causality with the Hilbert-Huang Transform

Figure 3

IIC based on the IMF pairs cross-spectrum is computed for each time point. Spectral resolution was set to 1 Hz for visualization effects. Positive values of IIC from time series 1 to 2 at 10 Hz can be observed. End effects are present due to the EEMD.
