Webof the test, there is hardly a reason to use it in internal model validation processes when there are more powerful approaches available. In addition to the acceptable amount of exceptions, another equally important aspect is to make sure that the observations exceeding VaR levels are serially independent, i.e. spread evenly over time. Web1. Backtesting VaR. 定义：Backtesting回测VaR，是验证实际损失与预测损失（历史数据的预测）的数量是否吻合。. 如果模型完善，超过VaR的天数（Exceedances或者Exceptions），与置信水平相当，如果Exceptions过多，即VaR定太小了，即低估了风险；如果Exceptions太少，即VaR定太 ...
