This model belongs to the class of threshold-autoregressive models, where changes in regimes are governed by past returns. The ability to capture changes in volatility regimes and using more accurate volatility measures allow outperforming other benchmark models, such … 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. north glynn

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 ...

WebIts robustness property means that if we have a stochastic volatility plus infrequent jumps process, then the difference between realized variance and realized bipower variation estimates the quadratic variation of the jump component. This seems to be the first method that can separate quadratic variation into its continuous and jump components.
