cross-correlation
cross-correlation Cross-correlation is a method used to estimate how strongly two time-based signals are related, often in studies of behavioral or physiological synchrony.
Cross-correlation is a method used to estimate how strongly two time-based signals are related, often in studies of behavioral or physiological synchrony. It produces a correlation value from -1 to 1 that indicates positive or negative coupling, but it works best when the relationship is roughly linear and the signals do not show problematic non-stationarity or strong autocorrelation.
