题目
A big part of a risk manager's job is to identify her firm's risk factors. Each of the following statements about risk factors is true EXCEPT which is false?
选项
A.Two examples of primary risk factors include the return on a broad stock market index and the risk-free spot interest rate.
B.For any risk factors that are represented by categorical or discrete variables, the risk manager should seek to replace them with either interval, ratio, or continuous risk factor variables.
C.One of the risk manager's key activities is to deconstruct primitive risk factors into the important loss drivers, the relationship of the loss drivers with each other, and the wider business environment.
D.Machine learning, as a subset of artificial intelligence, holds the potential to help risk managers identify the "unknown unknowns".
答案
B
解析
Instead, many risk factors are characterized by categorical or discrete variables.In terms of option D, GARP writes, "Across the risk industries, massive computing power can now help risk managers spot patterns and relationships in data more quickly. Unsupervised machine learning can help the risk manager identify the unknown unknowns through identifying clusters and correlations without specifying the area of interest in advance. Risk managers are about to enter an age of plenty in terms of data volume and risk factor analysis." 相反，许多风险因素的特征是分类变量或离散变量。 关于选项D，GARP写道：“在整个风险行业中，强大的计算能力现在可以帮助风险管理人员更快地发现数据中的模式和关系。无监督机器学习可以帮助风险管理人员通过识别聚类和相关性来识别未知的未知数，而无需预先指定感兴趣的领域。就数据量和风险因素分析而言，风险管理者将进入一个新时代。”
