class CONNECTIVITYLIB::DebiasedSquaredWeightedPhaseLagIndex

Computes the debiased squared Weighted Phase Lag Index of Vinck et al.

(NeuroImage 2011) for every channel pair.

The estimator subtracts the analytically known diagonal variance from both numerator and denominator of WeightedPhaseLagIndex, producing an estimator whose expectation equals wPLI^2 even for very small trial counts. It is the preferred PLI-family metric when the number of trials is low and is the volume-conduction-robust counterpart of magnitude-squared coherence.

Debiased squared Weighted Phase Lag Index (Vinck et al. 2011); low-bias volume-conduction-robust estimator.
