Fur-thermore, Granger causality assumes that the two time se-ries under consideration have a linear relationship with time-lagged values and additive noise present. The mathematical model for Granger causality among two time ...

J. … 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 … See more We say that a variable X that evolves over time Granger-causes another evolving variable Y if predictions of the value of Y based on its own past values and on the past values of X are better than predictions of Y … See more If a time series is a stationary process, the test is performed using the level values of two (or more) variables.
