pybic.SpecToTrispec

pybic.SpecToTrispec(spec, v=[0, 0, 0], lilguy=1e-06)[source]

Estimate auto-trispectrum/-tricoherence spectrum from spectrogram(s).

Parameters:

spec (ndarray) – Input spectrogram.
v (list of int) – List of time-series’ indices to analyze.
lilguy (float) – Small value to avoid 0/0 errors.

Returns:

t2,T = SpecToTrispec(...)

t2 (ndarray) - Tricoherence spectrum.
T (ndarray) - Trispectrum.

Return type:
