The dynamics of hourly electricity prices

Härdle, Wolfgang Karl; Trück, Stefan - 2010

The dynamics of hourly electricity prices in day-ahead markets is an important element of competitive power markets that were only established in the last decade. In electricity markets, the market microstructure does not allow for continuous trading, since operators require advance notice in...

Optimal Smoothing for aComputationally andStatistically Efficient SingleIndex Estimator

Xia, Yingcun; Härdle, Wolfgang; Linton, Oliver - Sonderforschungsbereich Ökonomisches Risiko <Berlin> - 2009

In semiparametric models it is a common approach to under-smooth the nonparametric functions inorder that estimators of the finite dimensional parameters can achieve root-n consistency. The requirementof under-smoothing may result as we show from inefficient estimation methods or technical...

Constrained general regression in pseudo-Sobolev spaces with application to option pricing

Hlávka, Zdeněk; Peésta, Michal - 2006

State price density (SPD) contains important information concerning market expectations. In existing literature, a constrained estimator of the SPD is found by nonlinear least squares in a suitable Sobolev space. We improve the behavior of this estimator by implementing a covariance structure...

Integrable e-lements for statistics education

Härdle, Wolfgang Karl; Klinke, Sigbert; Ziegenhagen, Uwe - 2005

Without doubt modern education in statistics must involve practical, computer-based data analysis but the question arises whether and how computational elements should be integrated into the canon of methodological education. Should the student see and study high-level programming code right at...

Using Wiki to build an e-learning system in statistics in Arabic language

Ahmad, Taleb; Härdle, Wolfgang Karl; Klinke, Sigbert - 2007

E-learning plays an important role in education as it supports online education via computer networks and provides educational services by utilising information technologies. We present a case study describing the development of an Arabic language elearning course in statistics. Discussed are...
