Can you provide any resources about the theory behind high order spectra analysis of time series?

Hello Trichter,

Thanks for your code. I was wondering if you can suggest any intuitive (ideally not too mathematical) references on high order spectra analysis. I am working with time series recorded from the brain.

Thanks in advance :)

Hi,

sorry, I cannot provide a good reference. I only googled my way through the theory. If you find a good reference, please post it here. Thanks.

Hello Trichter, Thanks for your code. I am a researcher studying heart sound signals, and your code is very useful. But I don't understand the principle behind its implementation. Can you provide me with your reference material? I haven't found any relevant information on converting from spectrogram to bispectrum
