VaR 计算练习

Lesson Overview

In "Quant Risk Framework" → "VaR 框架", this lesson "VaR 计算练习" builds knowledge you can apply immediately.

VaR实操要验证单调、符号和小样本边界。代码返回数字不代表输入有意义，无数据、非有限值和错误置信水平应拒绝。 运行自检→手算10项样例→改95%再算→测试空数组/NaN→输出算法与错误，不吞异常。 本课作业：同样10项损失求95%nearest-rank VaR；置信度1.2和空样本怎样处理？

Core Concepts

These points align with the video walkthrough—take notes as you watch.
