WebThe Granger causality test is a statistical hypothesis test for determining whether one time series is useful in forecasting another, first proposed in 1969. Ordinarily, regressions reflect "mere" correlations, but Clive Granger argued that causality in economics could be tested for by measuring the ability to predict the future values of a time series using prior values … Webtest can be applied: • In a simple Granger-causality test there are two variables and their lags. • In a multivariate Granger-causality test more than two variables are included, because it is supposed that more than one variable can inﬂu-ence the results. • Finally Granger-causality can also be tested in a VAR framework, in
