A generic architecture for hybrid intelligent systems
Jacobsen, Hans-Arno - 1998
The integration of different learning and adaptation techniques in one architecture, to overcome individual limitations and achieve synergetic effects through hybridization or fusion of these techniques, has in recent years contributed to a large number of new intelligent system designs. Most of...

The influence of inventory effects and reference points on the rate of consumption
Bell, David R.; Boztuğ, Yasemin - 2001 - Rev.
The authors develop and test a model to study the influence of inventory-on-hand and price-based reference points on … positive and negative deviations from category price expectations. The model is estimated on eleven product categories. The …

Price variability and price dispersion in a stable monetary environment : evidence from German retail markets
Fengler, Matthias R.; Winter, Joachim - 2000
We investigate the relationship between inflation and price variation using highly disaggregated, weekly price data for … rates of price change and price dispersion, both at the level of individual products and product groups. However, we find no … correlation between the rates of price change and price variability. Together with results from similar studies, Tommasi (1993 …

A note on stochastic volatility, GARCH models, and hyperbolic distributions
Jaschke, Stefan R. - 1997
We establish a relation between stochastic volatility models and the class of generalized hyperbolic distributions. These distributions have been found to fit exceptionally well to the empirical distribution of stock returns. We review the background of hyperbolic distributions and prove...

Flexible stochastic volatility structures for high frequency financial data
Feldmann, David; Härdle, Wolfgang; Hafner, Christian M.; … - 1998
Stochastic Volatility (SV) models are widely used in financial applications. To decide whether standard parametric restrictions are justified for a given dataset, a statistical test is required. In this paper, we develop such a test based on the linear state space representation. We provide a...

Testing for short and long-run causality : the case of the yield spread and economic growth
Breitung, Jörg; Candelon, Bertrand - 2001
To assess the predictive content of the interest rate term spread for future economic growth, we distinguish short-run from long-run predictability by using two different approaches. First, following Dufour and Renault (1998) a test procedure is proposed to test for causality at different...
