WebOct 7, 2024 · Granger’s causality Tests the null hypothesis that the coefficients of past values in the regression equation is zero. So, if the p-value obtained from the test is lesser than the significance level of 0.05, then, you can safely reject the null hypothesis. This has been performed on original data-set. Below piece of code taken from stackoverflow. 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. on the potential
