Web1We consider estimators using bipower increments with threshold, which will be referred to as threshold-bipower estimators, in Sections 3 and 4. However, for the simulation and empirical studies in Section 5, we also use the estimator using bipower increments without threshold truncation, that is, bipower estimators. Within our framework, http://www.ichacha.net/bias%20power.html
WebThe bipower variation process of order (r;s) for Y, denoted by V(Y;r;s)t, is the limit in probability, if it exists for all t 0, of V(Y;r;s)n t. It has been introduced in [4] and [5], where it is shown that the bipower variation processes exist for all nonnegative indices r;sas soon as Y is a continuous semimartingale WebRBPV的定义，RBPV是什么意思，RBPV的意思，实现的 Bipower 变化，RBPV代表的意义实现的 Bipower 变化
WebRealised bipower variation consistently estimates the quadratic variation of the contin-uous component of prices. In this paper we generalise this concept to realised bipower … WebDec 1, 2014 · We extend the classical bipower variation estimation method to the correlated return process. When the return process is correlated, our method provides a …
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.
