Granger causality - Wikipedia
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. If the variables are non-stationary, … See more A method for Granger causality has been developed that is not sensitive to deviations from the assumption that the error term is normally distributed. This method is … See more • Bradford Hill criteria – Criteria for measuring cause and effect • Transfer entropy – measure the amount of directed (time-asymmetric) transfer of information See more As its name implies, Granger causality is not necessarily true causality. In fact, the Granger-causality tests fulfill only the Humean definition of causality See more A long-held belief about neural function maintained that different areas of the brain were task specific; that the structural connectivity local to a certain area somehow dictated the function of that piece.

A variable X is said to be Granger-causing a target variable Y if past values of X contain information that helps predict Y beyond the information that is contained in past values of Y.
