讲座内容简介：

In this paper, we concentrate on the asymptotic expansion for a class of normalized L-statistics. By the change of measure method and asymptotic analysis techniques, we can obtain the sharp large deviations for the above mentioned L-statistics. Finally, our results could be applied to Gini, Fortiana-Grané and Jackson statistics. From the simulation study, we can see that the approximations obtained from the obtained sharp large deviations are very accurate for small tail probabilities.
