基础班墨迹版讲义 P185 说 Binomial Valuation process assumes cash flows are independent of the path while Monte Carlo methods are often used when cf are dependent.
P203 最后一句说arbitrage free model can be used to value optional bonds
optional bonds 的cash flow 是dependent on interest rate path 的,而arbitrage free model 是binomial model的一种,那么这里不是与185页的内容矛盾了吗?
