Since correlation may be interpreted as a measure of the influence across time-series, it may be conveniently mapped … noise in correlation matrices by extracting the dominant hierarchy (i.e. the strongest linear-dependence signals) within … structural shift caused by the failure of Lehman Brothers. Thus, based on two different correlation-into-distance mapping …
