WebAug 23, 2012 · Granger causality is a statistical concept of causality that is based on prediction. According to Granger causality, if a signal X 1 "Granger-causes" (or "G-causes") a signal X 2, then past values of X 1 should contain information that helps predict X 2 above and beyond the information contained in past values of X 2 alone.
