英文摘要:
  Motivated by the Basel 3 regulations, recent studies have considered joint forecasts of Value-at-Risk and Expected Shortfall. A large family of scoring functions can be used to evaluate forecast performance in this context. However, little intuitive or empirical guidance is currently available, which renders the choice of scoring function awkward in practice. We therefore develop graphical checks (Murphy diagrams) of whether one forecast method dominates another under a relevant class of scoring functions, and propose an associated hypothesis test. We illustrate these tools with simulation examples and an empirical analysis of S&P 500 and DAX returns.

中文摘要:
受巴塞尔协议3规定的推动,最近的研究考虑了风险价值和预期缺口的联合预测。在这种情况下,可以使用一大系列评分函数来评估预测性能。然而,目前缺乏直观或经验指导,这使得评分函数的选择在实践中很尴尬。因此,我们开发了图形检查(墨菲图),以确定在相关的评分函数类别下,一种预测方法是否主导另一种预测方法,并提出了相关的假设检验。我们通过模拟示例和对标准普尔500指数和DAX收益率的实证分析来说明这些工具。
