[FieldTrip] Granger Causality

Hello,

I am following the connectivity tutorial to perform granger causality
analysis on iEEG data.  Please help me understand a few things:

1. Please clarify exactly what the output values of the granger matrix
represent. If I understand correctly, it is the log(variance of predicted
time course/variance of actual time course).

2. What range of values should I be getting for granger causality for iEEG
data? I am getting values ranging from 0 to 2.5. Values I see reported in
papers seem to report peaks barley higher than 1.

Thank you for your help!
Olga
