Granger causality test null hypothesis
)
Granger causality is a way to investigate causality between two variables in a time series. The method is a probabilistic account of causality; it uses empirical data sets to find patterns of correlation. Causality is closely related to the idea of cause-and-effect, although it isn’t exactly the same. A variable X is causal to variable … See more Granger causality is a “bottom up” procedure, where the assumption is that the data-generating processes in any time series are independent variables; then the data sets are … See more The null hypothesis for the test is that lagged x-values do not explain the variation in y. In other words, it assumes that x(t) doesn’t … See more If you have a large number of variables and lags, your F-test can lose power. An alternative would be to run a chi-square test, constructed with likelihood ratio or Wald tests.
