Abstract:

One improved Hill estimator using GLS(general least squares) is introduced, which overcomes some defects of Hill estimator, and is used to evaluate VaR. The VaR of index of Shanghai Composite, Hang seng, Dow Jones, Nasdaq, Nikkei are estimated and compared, and a simple analysis of the result is given.

Key words: Value at Risk, Hill estimator, GLS(general least squares), tail index, order statistics
