WebIn this study, we use a parametric time-frequency representation of vector autoregressive Granger causality for causal inference. We first show that causal inference using time-frequency domain analysis outperforms time-domain analysis when dealing with time series that contain periodic components, trends, or noise. WebIntroduction. What follows is a brief introduction to the concept of causality, leading into an outline of Granger-causality, as detailed in Clive Granger’s 1980 article, “Testing for causality A personal viewpoint”, published in the Journal of Economic Dynamics and Control (Vol.2, pp.329-352). Much of the research conducted about the ...
