Estimate Gaussianity using NegEntropy or Kurtoisis for Independent Components

Dear All,

I am wishing to know how can I estimate the measure of gaussianity (either by using Negentropy or Kurtoisis) for the Independent components extracted from the EEG data in MATLAB?

I tried to get some references using the documentation and existing threads, it seems a challenge for me.

Thanks

Kind regards,

Marimuthu
