Annualized convecity怎么算？公式怎么样的？

嗨，努力学习的PZer你好：
1、原版书上关于annualized convexity的相关计算，只给出了Convexity of Cash Flows的计算公式。有了每一期现金流的convexity之后，将它们加总起来，再除以一年计息次数的平方，即可得到annualized convexity。由于计算量太大，个人认为在考试中不会考察一整道题，要么计算其中的一小步，要么就是题目已经给出了sum，相当于做了一个简化。
2、回到本题，第七栏就是我们下方的公式，计算出每一期现金流的convexity，全部加总后得到206.68136，在此基础上除以4，得到51.67034。因为债券是一年付息两次，2的平方，所以除以4。
