Power and Bipower Variation With Stochastic Volatility and Jumps

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.

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. WebHowever, as the Bipower variation and the realized volatility exhibit similar char-acteristics (see Section 2.2.2) we can adopt the approaches developed for realized volatility models to the Bipower variation. We therefore start the discussion of our multivariate model with the specification of the Bipower variation equation, proceed with the ...
