Bipower volatility
WebTo this purpose, we introduce the concept of threshold bipower variation, which is based on the joint use of bipower variation and threshold estimation. We show that its generalization (threshold multipower variation) admits a feasible central limit theorem in the presence of jumps and provides less biased estimates, with respect to the ... Webvolatility and associated tools for its measurement, modeling, and fore-casting. In this chapter we suggest practical applications of recent developments in financial econometrics dealing with time-varying volatility to the mea-surement and management of market risk, stressing parsimonious models that are easily estimated.
