The Granger causality test is a statistical hypothesis test for determining whether one time series is useful in forecasting another, first proposed in 1969. and NBER ( [email protected] ) Abstract: We consider the forecasting of cointegrated variables, and we show that at long horizons nothing is lost by ignoring cointegration when forecasts are evaluated using standard multivariate forecast accuracy measures.

Johansen test. The Johansen test is a test for cointegration that allows for more than one cointegrating relationship, unlike the Engle–Granger method, but this test is subject to asymptotic properties, i.e. large samples. If the sample size is too small then the results will not be reliable and one should use Auto Regressive Distributed Lags (ARDL).

Interpreting Granger causality test’s results. The cross-correlation function is just the correlation of one time series versus a lagged version of the other, and the auto-correlation is just the cross-correlation of a function and itself. Thus these plots show the time structure of the strength of the linear relationships both internally (auto).
