Normalised bispectrum of higher order spectra

Hi, I am working on Higher order spectra (bispectrum). I have calculated the bispectrum using the toolbox command([bspec, waxis] = bispeci(y, nlag, samp_seg, overlap, flag, wind)). After this i want to calculate the normalized bispectrum. Is there a way to normalize bispectrum giving the bounded values between (0-1)??

Sir,

I read your paper titled "Detection of emotions in Parkinson's disease using higher order spectral features from brain's electrical activity" - 11/2014.

I am working on a similar problem and I require to compute the normalized bispectral entropy and normalized bispectral squared entropy.

Is it necessary to normalize the bispectrum to the interval [0-1] to calculate the above mentioned features? If so, is there an in built function that computes the same?

Hi, I am working on EEG signals, and I wanted to know whether there is any built in functions to compute the normalized bispectral entropy and normalized bispectral squared entropy. I am new to this field and I am not able to compute the entropies.

Thanks!
