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 … 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.

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 ... WebSummary. In the framework of stochastic volatility models there is a wide range of applications of power, bipower and multipower variation, i.e. the sum of appropriately scaled absolute values of log-returns and neighbouring log-returns raised to a certain power. Given high frequency data we can use the concept of power and multipower variation ...

WebThis paper provides limit distribution results for power variation, that is, sums of powers of absolute increments under nonequidistant subdivisions of time and for certain types of time-changed Brownian motion and α -stable processes. Special cases of these processes are stochastic volatility models used extensively in financial econometrics.
