WebOct 7, 2024 · Granger’s Causality Test: The formal definition of Granger causality can be explained as, whether past values of x aid in the prediction of yt, conditional on having already accounted for the effects on yt of past values of y (and perhaps of past values of other variables). If they do, the x is said to “Granger cause” y. The 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 of another time series. Since the qu…
