Bipower variation python
Webrealized bipower variation BVt. It has been stated in Barndorff-Nielsen and Shephard (2004); Ghysels et al. (2006) that the use of absolute return (and realized bipower variation) could capture the volatility better. 3. Numerical results In this section, we perform the model fitting and selection on all 6 stocks, using models mentionedabove. 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

WebDec 1, 2010 · Bipower variation is substantially biased if there is one jump in the trajectory (+48.04%) and greatly biased (+102.03%) if there are two jumps in the trajectory. 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).
