Modeling and Forecasting the Distribution of Energy Forward Returns - Evidence from the Nordic Power Exchange

Lunde, Asger; Olesen, Kasper V. - School of Economics and Management, University of Aarhus - 2014

analyze empirical results for a selection of existing realized measures of volatility and incorporate them in a Realized GARCH … documented, which motivates the use of a flexible and robust methodology such as the Realized GARCH. Within this framework …-of-sample results for the Realized GARCH forecasts suggest a limited added value from using “traditional” realized volatility measures …

A Range-Based Test for the Parametric Form of the Volatility in Diffusion Models

Podolskij, Mark; Ziggel, Daniel - School of Economics and Management, University of Aarhus - 2007

We propose a new test for the parametric form of the volatility function in continuous time diffusion models of the type dXt = a(t,Xt)dt + s(t,Xt)dWt. Our approach involves a range-based estimation of the integrated volatility and the integrated quarticity, which are used to construct the test...

Bipower-type estimation in a noisy diffusion setting

Podolskij, Mark; Vetter, Mathias - School of Economics and Management, University of Aarhus - 2008

We consider a new class of estimators for volatility functionals in the setting of frequently observed Itô diffusions which are disturbed by i.i.d. noise. These statistics extend the approach of pre-averaging as a general method for the estimation of the integrated volatility in the presence of...

A Range-Based Test for the Parametric Form of the Volatility in Diffusion Models

Podolskij, Mark; Ziggel, Daniel - School of Economics and Management, University of Aarhus - 2008

We propose a new test for the parametric form of the volatility function in continuous time diffusion models of the type dXt = a(t;Xt)dt + _(t;Xt)dWt. Our approach involves a range-based estimation of the integrated volatility and the integrated quarticity, which are used to construct the test...

Estimation of Volatility Functionals in the Simultaneous Presence of Microstructure Noise and Jumps

Podolskij, Mark; Vetter, Mathias - School of Economics and Management, University of Aarhus - 2007

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...

Realized GARCH: A Complete Model of Returns and Realized Measures of Volatility

Hansen, Peter Reinhard; Zhuo (Albert) Huang; Shek, … - School of Economics and Management, University of Aarhus

GARCH models have been successful in modeling financial returns. Still, much is to be gained by incorporating a … and realized measures of volatility. The Realized GARCH framework nests most GARCH models as special cases and is, in many … ways, a natural extension of standard GARCH models. We pay special attention to linear and log-linear Realized GARCH …
