WebCausality between two variables X and Y can be proved with the use of the so-called Granger causality test, named after the British econometrician Sir Clive Granger.This test makes use of Student's t-statistic and F-statistic tests and testifies when values of the variable X provide statistically significant information about the evolution of the future … Webthe right inference of one-period ahead causality patterns. The possibility to test Granger causality from the low frequency process y to the high frequency processes x brings us to the second illustrative example.
