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 (
Coherencefor the absolute value,Coherencyfor the complex value) - Phase locking value, a.k.a. the mean resultant vector length or R̄ (
PLV) - Pairwise phase consistency, a.k.a. the unbiased estimator of R̄^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.
