class CONNECTIVITYLIB::Correlation

Computes the trial-averaged Pearson correlation coefficient between every channel pair from the raw time-domain trial data.

Per-trial correlation matrices are computed in parallel via QtConcurrent::mappedReduced and summed in reduce. The result is a symmetric matrix in ``[-1, 1]; it is broadband, zero-lag and does not reject volume conduction, so it is mainly useful as a baseline against the spectral and phase-based estimators.

Pearson correlation estimator; broadband, zero-lag time-domain baseline.
