考点Expected Shortfall
解析An estimate of the expected shortfall can be obtained by taking the average of the VaRs for the various confidence levels that are greater than 97.5%.This leads to an estimate of USD 1,023,000,000.
看了之前有同学的提问,但是还是没太理解
区别就在于loss的ES和VaR的ES,而VaR是在一个loss的分布里得出来的。那跟要不要把分位点上这个数排除出去有啥关系呢
