Our analysis shows that it is important to have a reasonable yardstick to assess the relative merits of competing models. Based on the viewpoint of a hedger, we recommend the hedging error to be the loss function in judging out-of-sample performance.

我们的分析显示用一个合理的评价标准去衡量不同模型间相对优点是相当重要的，基於避险者的角度，我们建议使用避险误差作为损失函数来评定样本外的绩效。
