WebApr 19, 2024 · I am doing Granger Causality test and I want to know about the lag selection. I am using 'forvalues' to find out the optimal lag length. When I use the 'forvalues' command, it gives a different lag length with each variable. For example, Y → X (lag 2, based on AIC), X → Y (lag 3). In my understanding, with each direction (Y → X, X →Y ...

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.
