Web17 de mar. de 2014 · Here causality is measured by the time rate of change of information flowing from one series, say, X2, to another, X1. The measure is asymmetric between the two parties and, particularly, if the process underlying X1 does not depend on X2, then the resulting causality from X2 to X1 vanishes. The formula is tight in form, involving only the ... WebAnother important application of Liang-Kleeman information flow is the establishment of a quantitative and rigorous causality analysis. Given two time series X 1 and X 2, (Liang 2014) proved that the maximum likelihood estimator of the information flowing from X 2 to X 1 is:. where C i,j is the covariance between X i and X j, and C i,dj that between X i and … cic filter synthesis
