近似分布 meaning in Chinese
approximate distribution
approximation to distribution
Examples
- The approximation of the distribution is justified by looking at two correlation coefficients
通过计算两类相关系数，证明了该近似分布函数的合理性。 - It is proved that as the number of insured tends to infinity the average prospective loss random variable of this portfolio tends in probability to a certain random variable of which the approximate distribution function is derived
证明了当保单数趋于无穷多时，平均损失变量按概率收敛于某一个随机变量，推导得到了该随机变量的近似分布函数。 - Evading risk in financial trading market cries for pricing options to a nicety . asian option , as the most flourish options in the finace market , the pricing has been focused on always . the exact pricing formula for the geometric average asian option had existed , but as to the european - style arithmetic average asian option , due to the dependence structure between the prices of the underlying asset , no analytical formula exists . on the hypothesis that the market is frictionless and without transaction costs 、 on the base of b - s ’ s and in the binomial tree model , we provide several algorithms for computing an accurate value of the european - style arithmetic average asian option . following rogers and shi and by jensen ’ s inequality , many different upper and lower bounds are provided ; meanwhile a formula have got by the comonotonicity and approximating the distribution function . all of the algorithms are easy for programming . with the development of computer , more accurater price can be computed quickly . and numerical example proved that these algorithms are very accurate
对于几何平均亚式期权它的定价相对简单,已经给出了定价公式。对于算术平均亚式期权,它的未定权益具有轨道依赖特性,一直没有得到它的定价方程的解析解形式。本文基于对市场是无摩擦且在没有交易费用的情况下,在b - s模型下,利用二叉树模型给出了算术平均亚式期权定价方法;并总结了利用jensen ’ s不等式给出的各种不同情况下的上下界;同时应用共单调性和近似分布函数的方法也给出了算术平均亚式期权价格的近似公式。
