Normalizing the causality between time series
WebHere causality is measured by the time rate of information flowing from one series to the other. The resulting formula is tight in form, involving only commonly used statistics, … Web15 de jan. de 2015 · To assess the importance of a resulting causality, it needs to be normalized. The normalization is achieved through distinguishing three types of fundamental mechanisms that govern the marginal entropy change of the flow recipient.

Based on a recently rigorized … Webwhere we are interested in approximating non-symmetrical dependencies between variables, causality is more adequate than correlation measures. In the literature, two main causality measures have been well investigated in the field of time series analysis; the Granger causality test (Granger,1980), and the Transfer entropy (Schreiber,2000). The

WebCausality is the ability to infer a counterfactual difference in outcomes given you experimentally manipulate ("do") an exposure in a hypothetical research setting. Instead, if you wish to measure how "instantaneously related" two time series are, calculate the cross-correlation of the two time series.
