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 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.
