WebThe causality lags are thus seen to be correct and the causality coherences to be reasonable. In particular, if b = 0 then C-(w) = 0, i.e., no causality is found when none is present. (Further, in this new case, 4/-(w) = 0.) ' A discussion of the interpretation of phase diagrams in terms of time lags may be found in Granger and Hatanaka [4 ... WebDetecting causal interrelationships in multivariate systems, in terms of the Granger-causality concept, is of major interest for applications in many fields. Analyzing all the relevant components of a system is almost impossible, which contrasts with the concept of Granger causality. Not observing some components might, in turn, lead to misleading …
