D) ES is relatively easier to backtest than VaR.
答案:A
解析:ES is slowly gaining popularity among financial risk managers. Despite criticism focused on the complexity, computational burden, and backtesting issues associated with expected shortfall, the recent literature suggests that many issues have been resolved or have been identified as less severe than originally expected, including improvements in backtesting methodologies. VaR has been criticized for its lack of subadditivity. Expected shortfall is subadditive.

A) Testing an empirical distribution from a theoretical distribution.
B) Testing a theoretical distribution from an empirical distribution.
C) Identifying an empirical distribution from a theoretical distribution.
D) Identifying a theoretical distribution from an empirical distribution.
解析:Once a sample is obtained, it can be compared to a reference distribution for possible identification. The QQ plot maps the quantiles one to one. If the relationship is close to linear, then a match for the empirical distribution is found. The QQ plot is used for visual inspection only without any formal statistical test.
