请问这个知识点的计算题是需要掌握的吗?

NO.PZ2023091701000163

问题如下:

Company A uses a Pareto distribution to model the loss severity of its low-frequency, high-severity operational risk events. A Pareto distribution has the following properties, given parameter Xm and k:

Mean:, for k1

Variance:, for k2

Cumulative distribution function:

After fitting the distribution to historical loss data, the parameters are estimated as k = 2.4, Xm = 10,000. What is the unexpected loss of a low-frequency, high severity operational risk event at 99% confidence level?

选项:

A.40703 B.23560 C.50986 D.68129

解释:

The first step, we must get the E(X). So k = 2.4, Xm = 10,000, Mean = 17143;

The second step, we must get the X. So,

The third step, Unexpected Loss = VaR = X – E(X) = 50,986.

还是仅仅了解即可?
