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 … WebApr 6, 2024 · The EEG data were analyzed using the open-source EEGLAB toolbox in MATLAB, as described by Delorme and Makeig (2004) .
