Granger causality test p value
WebDetails. Currently, the methods for the generic function grangertest only perform tests for Granger causality in bivariate series. The test is simply a Wald test comparing the unrestricted model---in which y is explained by the lags (up to order order) of y and x ---and the restricted model---in which y is only explained by the lags of y. WebThe alternative is: ∃ \bold α 21, i ≠ 0 for i = 1, 2, …, p. The test statistic is distributed as F ( p K 1 K 2, K T − n ∗), with n ∗ equal to the total number of parameters in the above VAR (p) (including deterministic regressors). The null hypothesis for instantaneous causality is defined as: H 0: C \bold σ = 0, where C is a ( N ...
