Noise Reduction in a Reputation Index
International Journal of Financial Studies, 2018 Assuming that a time series incorporates “signal” and “noise” components, we propose a method to estimate the extent of the “noise” component by considering the smoothing properties of the state-space of the time series. A mild degree of smoothing in the
