Lag selection is about obtaining a "good" model, where "good" could have different meanings, e.g. efficient in forecasting (as due to AIC) or consistently selected (as due to BIC). Given a selected model, you then test for Granger causality. WebOct 12, 2015 · In the end, we find that lag = 2 is the best fit according to AIC and BIC. We subsequently test for Granger causality (Wald-test) and indeed we find a causality ( X → Y 0.04** vs Y → X 0.56). However, if we apply the Impulse Response Function (IRF) of the VAR, we see that the most significant shock seems to be at lag = 4. on the rocks villa turks and caicos
