Analysis of synchronous signals

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.
