问题如下:
The distribution of the losses from a project over one year has a normal loss distribution with a mean of −10 and a standard deviation of 20. What is the one-year VaR when the confidence level is (a) 95%, (b) 99%, and (c) 99.9%?
解释:
(a) -10+1.645*20=22.9
(b) -10+2.33*20=36.6
(c) -10+3.09*20=51.8
一个项目的损失符合正态分布,mean=-10,σ=20,求1年的VaR当置信区间等于95%,99%,99.9%时。
95% VaR=-10+1.645*20=22.9
99% VaR=-10+2.33*20=36.6
99.9% VaR=-10+3.09*20=51.8
请补充损失分布下计算极端值的公式?感谢?
