The Delayed Poisson Shocks Model and IFRA Life Distribution

然后考虑到泊阿松跳过程带来的风险，又采用最小方差对冲策略将风险重新对冲，得到了期权定价方程。

Then , considering the risk bringed by Poisson jumps , the option pricing equation is gotten by minimal-variance hedging strategy .

西阿松说：“有人说，以前我们不是被烧了一次吗？当时我们正准备接受他们时，但没过几天，他们又打了起来。”

Siazon said ," some say , haven 't we been burnt before ? At that time , just as we were ready to accept them , they fought again several days later . "

采用邻接格子样方法取样，运用扩散系数作为聚集强度的测度指标，并进行泊阿松分布和负二项分布的Χ2拟合检验；

Sampling was conducted with the method of contiguous grid quadrate , Dispersion Index ( v / m ratio ) was taken as the index of aggregation intensity , and the simulation tests for Poisson and Negative binomial distribution were performed .
