If the two jumps are consecutive, the bias is huge (+595.57%) and can only be marginally softened by using staggered bipower variation (+97.07%, like for the case of two jumps).

Webcan be chosen among jump robust integrated variance estimators: rBPCov, rMinRVar, rMedRVar, rOWCov and corrected threshold bipower variation ( rThresholdCov ). If rThresholdCov is chosen, an argument of startV, start point of auxiliary estimators in threshold estimation can be included. rBPCov by default. IQestimator WebIts robustness property means that if we have a stochastic volatility plus infrequent jumps process, then the difference between realized variance and realized bipower variation estimates the quadratic variation of the jump component. This seems to be the first method that can separate quadratic variation into its continuous and jump components.
WebApr 4, 2008 · With the aim of achieving this, 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 ...

Webquantities, called realized power variation and bipower variation, respectively, are both quite robust to rare jumps in the log-price process. In particular, we demonstrate that it is possible, in theory, to untangle the impact of the presence of volatility and rare jumps by using power and bipower variation. Realized bipower
WebJan 1, 2004 · This article shows that realized power variation and its extension, realized bipower variation, which we introduce here, are somewhat robust to rare jumps.
