On Comparison of the Estimators of the Hurst Index of the Solutions of Stochastic Differential Equations Driven by the Fractiona
This paper presents a study of the Hurst index estimation in the case of fractional Ornstein–Uhlenbeck and geometric Brownian motion models. The performance of the estimators is ...

Analysis and generation of random vectors with copulas
Copulas are used in finance and insurance for modeling stochastic dependency. They comprehend the entire dependence structure, not only the correlations. Here they are estimated ...

Practical aspects of simulating systems having arrival processes with long-range dependence
Analysis of network traffic indicates that packet arrival processes have significant stochastic dependence. It has been suggested that this dependence is so strong as to be wellmo...

Efficient decision ordering techniques for SAT-based test generation
Model checking techniques are promising for automated generation of directed tests. However, due to the prohibitively large time and resource requirements, conventional model chec...
