WebIn 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 Granger causality is based on the principle that a variable causes another variable if it contains useful information in terms of prediction.
