This package implements efficient multitaper and continuous wavelet transforms, along with the following transform statistics most of which operate on pairs of signals:
- Power spectral density (
PowerSpectrum
) - Power spectral density variance (
PowerSpectrumVariance
) - Cross spectrum (
CrossSpectrum
) - Coherence (
Coherence
for the absolute value,Coherency
for the complex value) - Phase locking value, a.k.a. the mean resultant vector length or RĖ (
PLV
) - Pairwise phase consistency, a.k.a. the unbiased estimator of RĖ^2 (
PPC
) - Phase lag index (
PLI
) - Unbiased squared phase lang index (
PLI2Unbiased
) - Weighted phase lag index (
WPLI
) - Debiased squared weighted phase lag index (
WPLI2Debiased
) - Jammalamadaka circular correlation coefficient (
JCircularCorrelation
) - Jupp-Mardia squared circular correlation coefficient (
JMCircularCorrelation
) - Hurtado et al. modulation index (phase-amplitude coupling) (
HurtadoModulationIndex
)
Additionally, the following point-field measures are implemented:
- Point-field coherence (
pfcoherence
) - Point-field PLV (
pfplv
) - Point-field PPC, variants 0, 1, and 2 (
pfppc0
,pfppc1
,pfppc2
)
And the following point-point measures:
- Point-point cross correlation (
pfxcorr
)
All measures except for the point-field measures have corresponding unit tests. Documentation is forthcoming.
