Title:

Mixed effect models for absolute log returns of ultra high frequency data

Document type:
Zeitschriftenaufsatz

Haug, S. and Czado, C.
Abstract:
Considering absolute log returns as a proxy for stochastic volatility, the influence of explanatory variables on absolute log returns of ultra high frequency data is analysed. The irregular time structure and time dependency of the data is captured by utilizing a continuous time ARMA(p,q) process. In particular we propose a mixed effect model for the absolute log returns. Explanatory variable information is used to model the fixed effects, whereas the error is decomposed in a non-negative Levy...     »
