Dear EEGLAB users
I am using below formula to calculate imaginary coherence. The imaginary coherence values are very small (under 0.1) from the below formula.
coh=Pxy/sqrt(Pxx * Pyy)
iCoh=abs(imag(coh))
My questions are:
1- Can we calculate imaginary coherence using EEGLAB without SIFT?
2- Why imaginary coherence values are very small?
3- How to interpret imaginary coherence results?
Thanks
Best Regards
Muhammad Abul Hasan
