请问这道题在课件的哪个地方有体现?

NO.PZ2016070202000005

问题如下:

Backtesting routinely compares daily profits and losses with model-generated risk measures to gauge the quality and accuracy of their risk measurement systems. The 1996 Market Risk Amendment describes the backtesting framework that is to accompany the internal models capital requirement. This backtesting framework involves

I.       The size of outliers

II.     The use of risk measure calibrated to a one-day holding period

III.   The size of outliers for a risk measure calibrated to a 10-day holding period

IV.    Number of outliers

选项:

A.

II and III

B.

II only

C.

I and II

D.

II and IV

解释:

D is correct. The backtesting framework in the IMA only counts the number of times a daily exception occurs (i.e., a loss worse than VAR). So, this involves the number of outliers and the daily VAR measure.

嗨,努力学习的PZer你好:


讲义65页左右的位置,通过记录超过银行算的var的次数,来进行惩罚。往后数2页就是上一题你问的那几个例外的位置~

NO.PZ2016070202000005 1. calibrateto a one-y holng perio2. calibrateto a ten-y holng perio我知道10天的VAR是通过ily VAR去推出来的,所以这两种说法感觉第二种更对吧?就是(通过ily)调整成10天期限的VAR。而不是说直接调整成1天期限的VAR。
