Granger Causality
A causality concept introduced by Nobel laureate Clive Granger in 1969. It defines causal influence by determining whether the historical information of variable X significantly reduces the prediction error for variable Y. In nature, it captures statistical dependency rather than mechanistic causation.

Clive Granger proposed Granger causality in 1969.
Granger causality is defined as: if including the historical information of variable X significantly reduces the prediction error for variable Y, then X is said to Granger-causally influence Y.
Granger causality is essentially a statistical dependence measure, cannot handle latent confounding variables, and cannot distinguish direct causation from indirect causation.
