WebDec 1, 2014 · Thus, when the returns are correlated as in high frequency financial markets, an estimator of return volatility which is robust to the existence of both jumps and serial … WebDec 8, 2006 · We propose a new concept of modulated bipower variation for diffusion models with microstructure noise. We show that this method provides simple estimates for such important quantities as integrated volatility or integrated quarticity. Under mild conditions the consistency of modulated bipower variation is proven. how to seal engineered stone

WebAbstract. This paper shows that realised power variation and its extension we introduce here called realised bipower variation is somewhat robust to rare jumps. We show realised bipower variation estimates integrated variance in SV models --- thus providing a model free and consistent alternative to realised variance. http://bipowerusa.com/ WebWe show realised bipower variation estimates integrated variance in SV models --- thus providing a model free and consistent alternative to realised variance.
