Journal ArticleDOI
Econometric analysis of realized volatility and its use in estimating stochastic volatility models
TL;DR: In this paper, the moments and the asymptotic distribution of the realized volatility error were derived under the assumption of a rather general stochastic volatility model, and the difference between realized volatility and the discretized integrated volatility (which is called actual volatility) were estimated.
Journal ArticleDOI
Non-Gaussian Ornstein–Uhlenbeck-based models and some of their uses in financial economics
TL;DR: The authors construct continuous time stochastic volatility models for financial assets where the volatility processes are superpositions of positive Ornstein-Uhlenbeck (OU) processes, and study these models in relation to financial data and theory.
Journal ArticleDOI
Power and Bipower Variation with Stochastic Volatility and Jumps
TL;DR: Barndorff-Nielsen and Shephard as mentioned in this paper showed that realized power variation and its extension, realized bipower variation, which they introduce here, are somewhat robust to rare jumps.
Journal ArticleDOI
Processes of normal inverse Gaussian type
TL;DR: A number of stochastic processes with normal inverse Gaussian marginals and various types of dependence structures are discussed, including Ornstein-Uhlenbeck type processes, superpositions of such processes and Stochastic volatility models in one and more dimensions.
Journal ArticleDOI
Designing realised kernels to measure the ex-post variation of equity prices in the presence of noise ∗
TL;DR: In this article, realised kernels are used to carry out efficient feasible inference on the expost variation of underlying equity prices in the presence of simple models of market frictions, where the weights can be chosen to achieve the best possible rate of convergence and to have an asymptotic variance which is close to that of the maximum likelihood estimator in the parametric version of this problem.
