WebGranger causality or G-causality is a measurable concept of causality or directed influence for time series data, defined using predictability and temporal precedence. A variable y G-causes another variable x if the prediction of x ’s values improves when we use past values of y, given that all other relevant information z is taken into account. 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 …
