multivariate granger causality in r

(c) Multivariate estimation of Granger causality: basic idea. Estimates all possible bivariate Granger causality tests for m variables.

In MTS: All-Purpose Toolkit for Analyzing Multivariate Time Series (MTS) and Estimating Multivariate Volatility Models. 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.. Description. Bivariate Granger causality tests for two variables X and Y evaluate whether the past values of X are useful for predicting Y once Y's history has been modeled. Causality is the agency of efficacy that connects one process (the cause) with another process or state (the effect), where the first is understood to be partly repsonsible for the second, and the second is dependent on the first.

It is based on spectral density matrix factorization and offers the advantage that the estimation of such a matrix needs to be done only once for the entire multivariate dataset. Here's one sample for a single dependent and independent variable based on an earlier question I asked and was answered by @Alex.

I'm having issues doing a multivariate Granger's causal test. In gegeral, a process has many causes, which are said to be causal factors for it, and all lie in its past. Performs Granger causality test using a vector autoregressive model Usage

For any subset of recorded data, Granger causality can be calculated

Currently, the methods for the generic function grangertest only perform tests for Granger causality in bivariate series. Granger's causality … Both methods are simply convenience interfaces to waldtest. Details.
