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.
WebApr 13, 2024 · In this paper, we propose a new approach to analyze financial contagion using a causality-based complex network and value-at-risk (VaR). We innovatively combine the use of VaR and an expected shortfall (ES)-based causality network with impulse response analysis to discover features of financial contagion. We improve the current … WebAug 9, 2024 · As stated here, in order to run a Granger Causality test, the time series' you are using must be stationary. A common way to achieve this is to transform both series by taking the first difference of each: x = np.diff (x) [1:] y = np.diff (y) [1:] Here is the comparison of Granger Causality results at lag 1 and lag 25 for the similar dataset I ...
