class CONNECTIVITYLIB::UnbiasedSquaredPhaseLagIndex

Computes the unbiased estimator of squared PLI for every channel pair.

The estimator subtracts the analytically known diagonal contribution from the squared sum of cross-spectral sign samples, yielding an estimate whose expectation equals PLI^2 for any trial count N >= 2 and is therefore free of the upward small-sample bias that affects the plain PhaseLagIndex. The construction preserves the zero-lag rejection property of the PLI family.

Unbiased squared Phase Lag Index estimator; removes the small-sample bias of PhaseLagIndex.
