pairwise granger causality clarification #31

Open saarangp opened 1 year ago

saarangp commented 1 year ago

Since the granger causality prediction is directed and asymmetric — I just wanted to be sure that my interpretation of the output is correct. In the output matrix, does [i,j] (row i, column j) correspond to i ---> j, or is it the other way around? Thanks!

I'm also uncertain about this. When inputting my data into FieldTrip (in Matlab), it seems to yield causality in the opposite direction. Could you kindly verify this? Thanks!
