WebMar 19, 2024 · Download PDF Abstract: We propose high-frequency volatility estimators with multiple change points that are $\ell_1$-regularized versions of two classical estimators: quadratic variation and bipower variation. We establish consistency of these estimators for the true unobserved volatility and the change points locations under general sub … 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 …

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 … WebFeb 29, 2008 · This article shows that realized power variation and its extension, realized bipower variation, which we introduce here, are somewhat robust to rare jumps. We demonstrate that in special cases, realized bipower variation estimates integrated variance in stochastic volatility models, thus providing a model-free and consistent alternative to ...
