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.

WebJun 29, 2024 · When testing for Granger causality: We test the null hypothesis of non-causality ( H 0: β 2, 1 = β 2, 2 = β 2, 3 = 0). The Wald test statistic follows a χ 2 distribution. We are more likely to reject the null hypothesis of non-causality as the test statistic gets larger. We should test both directions X ⇒ Y and X ⇐ Y.
