WebCausality between two variables X and Y can be proved with the use of the so-called Granger causality test, named after the British econometrician Sir Clive Granger.This … 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.
