嗨,爱思考的PZer你好:


这句话没有在讲义里直接说出来,这句话就是一个关于KMV模型的结论,建议同学直接记忆。

在这里其实是一个理解,莫顿模型是使用市场数据来估计违约概率的,KMV模型比莫顿模型的假设更加relax,所以KMV模型的这些数据也是从市场得到的。

KMV模型很重要,如果同学不是很理解具体的操作步骤,建议同学再去听一下基础班的课程,考试的时候绝对不会出讲义原文,大多是结论换个说法出来。

虽然现在很辛苦,但努力过的感觉真的很好,加油!

嗨,爱思考的PZer你好:


I credit risk+在基础讲义353页

II是描述KMVmodel是如何操作的,基础讲义180页开始

----------------------------------------------
努力的时光都是限量版,加油!

For KMV we can observe a firm’s asset value and volatility directly from the market, 这一描述是在第几页呢?

NO.PZ2020033003000020 In the KMV mol, we cobserve a firm’s asset value anvolatility rectly from the market, figures coulobtaineusing current equity value. 这个II 我觉得 有几个地方不太对呀? 我听过经典题&基础班了。。。但。。。 1. 不是说KMV不是观察到的asset value而是Monte Carlo模拟出来的吗? 2. 莫顿的确用了equity的BSM(current equity value),KMV是哪里用了Equity value呀?不就。。。先求个 然后安排上P然后再安排rating吗? 蟹蟹蟹蟹!
