WebDec 18, 2024 · Granger Causality and F statistic. I am trying to educate myself in Granger Causality reading the classic literature. From what I have understood the idea is quite simple: first, to test if X t Granger causes Y t we define two autoregressive models: (Full model) Y t = ∑ j = 1 p a j Y t − j + ∑ j = 1 q b j X t − j + ϵ t , (Reduced model ... WebTo create an F-test we will use these same variances, the variance explained (SSR), the variance unexplained, and the sum of squares total (SST). We first need to obtain the mean square before the F. To do that, we just need to know what the d.f. will be for dividing the Sum of Squares values (and our instructor always gives us that).
