Value at Risk Estimation are presented. The robustness and accuracy of these estimation methods are investigated based on the simulated and real data. In the backtesting procedure, the conditional coverage test (Christoffersen, Int. Econ. Rev. 39:841–862, 1998), the dynamic quantile test (Engle and Manganelli, J. Bus. Econ

Volatility Estimation Based on High-Frequency Datarecise than conventionally used volatility estimators, such as squared or absolute daily returns. The consistency of these estimators hinges on increasingly finer sampled high-frequency returns. In practice, however, the prices recorded at the very high frequency are contaminated by market microstru

Identifying Jumps in Asset Pricesith these equations, such as the requirement of continuity, they often provide adequate local fits to the observed asset price process. There are, however, several aspects of the empirical process that are not fit by simple diffusion equations.

Simulation-Based Estimation Methods for Financial Time Series Modelsconomics. The simulation-based methods have proven to be particularly useful when the likelihood function and moments do not have tractable forms and hence the maximum likelihood (ML) method and the generalized method of moments (GMM) are difficult to use. They are also useful for improving the fini

The purpose is to provide a survey and summary on each topic, ranging from basic background material through the current frontiers of research. The development of the field of computational statistics has been rather fragmented. We hope that the articles in th

Modeling driven by “memoryless homogeneous” jump processes (Lévy processes) constitutes one of the most viable directions in this enterprise. The basic principle is to replace the underlying Brownian motion of the Black-S
