问题如下:
Star Bank is backtesting its 95% confidence level VaR model, it uses the data of the past 750 trading days. How many expected exceptions are there in this backtesting?
选项:
A.12.5.
B.37.5.
C.5.
D.15.00.
解释:
B is correct.
考点:backtesting VaR
解析: (1 -0.95) x 750 =37.5
这个题是因为直接求个数,所以就750*0.05*0.95了,而公式里面的Z和x都是检验统计量,和实际的exception的个数无关是吗
