Abstract

A fast update algorithm for online calculation of the QnQn scale estimator is presented. This algorithm allows robust analysis of high-frequency time series in real time. It provides reliable estimates of a time-varying volatility even if many large outliers are present and it offers good efficiency in the case of clean Gaussian data.
