This paper aims to do this via regularized regressions using HAC-based inference. In a sense, we are trying to implement Granger’s original idea of causality.1 It is worth relating our work to the existing literature on Granger causality with high-

WebAug 17, 2024 · I've read that there is something called Granger causality tests and a PROC VARMAX command respectively, but I have yet too little knowledge to know if such tests are applicable in this case. Would it be possible (and perhaps foremost meaningful) to do a causality test in this case, and how could it then be done in SAS?
