Statistics of bicoherence
Steve Elgar, Robert T. Guza · IEEE Transactions on Acoustics Speech and Signal Processing · 1988
Numerical simulations are used to investigate statistics of biocoherence for the special case of a linear random process. Smoothed bicoherence statistics are shown to be independent of both the normalization used to form the bicoherence and of whether statistical stability is obtained by ensemble-averaging short records, or frequency merging within a long record.>
