假设值

It assumes survival time follow exponential distribution and quality of life initial value follow beta distribution. In order to correlate present quality of life with former quality of life, each quality of life were evaluations generated from AR(1) model. In addition, we set parameters of AR(1) model between 0 and 1, calculates expected QAST from different parameter combinations.

假设存活时间服从指数分布、生活品质初始值服从Beta分布，并利用时间序列一阶自我回归过程First-Order Autoregression Process， AR(1的模型产生各次生活品质评量值，使当次的生活品质与前一次的生活品质产生相关性，并将AR(1)模型中的参数设定为介於0与1之间的值，且产生不同的组合。

We get appropriate threshold with mean excess function plot, get severity distribution of losses over threshold with GPD and frequency distribution with hypothesis test.

首先根据均超函数图估计出恰当的阈值，利用假设检验估计超阈值的发生强度，用广义帕累托分布估计了超限参数。

A boundary integral method is adopted to simulate the bubble motion in the fluid field on the assumption that the fluid field is inviscid, irrotational and incompressible. A corresponding three-dimensional computation program is exploited and the calculated results agree well with the experimental data.

将气泡运动阶段周围的流场假设为无黏、无旋、不可压缩的理想流体，运用边界积分法模拟流场中气泡的运动，并开发了三维计算程序，计算值与实验值吻合较好。

In the verification stage, after each estimated transformation is applied, those medians of residual distances between the two mesh surface are calculated, and the transformation corresponding to the minimum is taken as the solution.

在刚体变换假设的验证阶段，计算施加每个变换后两个网格面之间的平方残余距离的中值，最终从中选择对应于最小值的刚体变换作为粗略配准问题的解。

You can omit either m or n; in that case, a reasonable value is assumed for the missing value.

你可以忽略 m 或 n；因为会为缺失的值假设一个合理的值。

You can omit either m or n; in that case, a reasonable value isassumed for the missing value.

你可以忽略 m 或 n；因为会为缺失的值假设一个合理的值。

Finally, we conclude that the value function of optimal switching control problem is a viscosity solution to this type QVI under some additional assumptions.

在这一章的最后在对值函数附加了一定的假设条件后还进一步地得到了最优切换控制问题的值函数是这类拟变分不等式粘性解的结论。

We use the data from BHP company in 1995-2001 and calculate the implied volatility. By comparing the implied volatility calculated from actual option price and the assumed volatility in the model, it is found that Black-Scholes Model does underprice the Out-of-The-Money options and overprice the In-The-Money options because of the wrong assumption on the volatility.

本文选择了澳大利亚BHP公司1995年-2001年其中五年的数据，从实际期权价格中计算得到隐含波动率，并把其与Black-Scholes模型中的假设波动率进行比较，最后可以发现，Black-Scholes模型低估了虚值期权的价格，高估了实值期权的价格，与一般的研究结果恰好相反。

In this paper, we use approximate distribution comes from probability generating function in estimating credit VaR. Further, we perform the credit VaR sensitive analysis for multi-sector factors based on different sector correlation assumption.

本文在信用风险加成模型之下，利用机率产生函数的近似分配计算信用风险值，并在多个部门因子中，在不同相关性部门因子分配假设下，比较信用风险值之敏感度分析。

These values are generally in good agreement with the proper motion velocities.

利用这些值并假设散射屏处在近似脉冲星和地球的中间，我们计算了7颗脉冲星的横向速度，这些值和自行速度吻合的很好。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
