Especially,when there are local changes among the data,and a single parametric distribution family can\'t describe the observed data accurately,finite mixing distribution models usually make excellent performance.

特别是，当观测数据有局部变化，而单一的参数分布族无法确切地描述观测数据时，有限混合分布模型表现出色。

In this paper,the research on the parameter estimation of Gamma distribution with three parameters and the test of the location parameters has been made.

该文考虑了混合分布为三参数伽玛分布时的参数估计以及位置参数的检验问题。

And the evaluation effects of China's Stock Market's volatility by different ARCH models from different point of view are compared. In addition, by using two mixed distribution models, the leptokurtosis and fat-tail of stock return are examined. Based on the above analysis, an improved Laplace distribution model is proposed. Furthermore, the root generating non-Gaussian return distribution of the stock market ? is expounded from the perspective of both economy and capital market.

首先分别从分布和波动性模型出发，研究中国股票市场收益分布特征与波动性特征：从ARCH族模型出发，考察了中国股票市场波动性的异方差、集群性、杠杆效应以及长记忆性特征；从两个混合分布模型出发，结合随机模拟考察了收益分布的尖峰、厚尾和偏态特征，并提出了改进型LapJace分布。

In order to reduce calculation error, the frequency distribution of average values is used to compute the mixed distribution's digital features of each component distribution, thereinto, the number of the component distribution is determined by AIC, choose the number that meets the minimum value of AIC as the component number of mixed distribution, and the other parameters are estimated by EM algorithm; Secondly, because each component distribution is corresponding to a kind of major gene genotype, according to the values of the average and variance of the each component distribution, we can use the limit error of the normal distribution to plot each individual into the correspondent component distribution, namely into correspondent major gene genotype. Then we regard each major gene genotype as a treatment level of one-way analysis of variances, and the one-way multivariate analysis of variance is carried out to calculate the covariance matrix of major gene effect, covariance matrix of polygene effect, covariance matrix of environment effect and so on; At last, combining the weights of the each component distribution of mixed distribution, we can calculate the variance of major gene effect, the variance of polygene effect, environmental variance and the genetic gain of the quantitative trait.

为减小计算误差，本研究采用均值的频数分布来计算各成分分布的数字特征，其中成分分布个数根据AIC准则，选择使AIC值达到最小的成分分布个数作为混合分布的成分分布数，分布中其它参数的确定利用EM算法来估计；其次，每个成分分布对应一种主基因基因型，根据各个成分分布的均值和方差，利用正态分布的极限误差将每个个体划分到相应的成分分布中，即相应的主基因基因型中，将每种主基因型作为单因素方差分析的一个处理水平，对其进行单因素的多元方差分析，分别计算主基因效应协方差阵、多基因效应协方差阵、环境协方差阵等参数；最后结合混合分布中各成分分布的权重即各主基因基因型的分离比例，计算主基因效应方差，多基因效应方差和环境方差，以及遗传力等参数，进而计算该数量性状的遗传进展。

Mix distribution hypnoses assume that the asset price movement and the trading volume are both determined by an unobservable flow of information; different pieces of information flowing into the security market will cause movements of both the trading volume and the price.

结果发现，与成熟的股票市场相比，中国股票价格波动的非对称性较弱，这可能是由于中国股票市场的特殊结构与贷款利率缺乏刚性所造成的。3，混合分布假说认为金融资产的收益和交易量是由一个潜在的不可观测的信息流变量共同决定的，信息流的冲击将同时产生收益和交易量的变动，即信息流是混合变量，日交易次数或交易量可以作为信息流的替代指标，所以交易量能够很好的解释价格波动性。

A frame image of a video frequency sequence is read into a postpositional memory zone, and staring position and size information of a tracked object is obtained in the frame, then distribution statistical information of a target signature is extracted to build a gauss mixed model as an object template, a mean vector and a covariance matrix in gauss mixed distribution are used to describe the position and the size of the object, then the next frame image of the video frequency sequence is read into the postpositional memory zone. In a new frame video frequency image, a parameter estimation method is used to obtain object gauss mized model parameters in the current frame in iterative computation and find candidate template similar to the object template, and the final model parameters obtained in iteration are used to update the tracking window for realizing self-adaption of the tracked window.

To avoid re-execution of the whole simulation system on condition that some nodes oragents are invalidated, a distributed simulation scheme with fault-tolerant mechanism isproposed, including fault classification, fault detection, the fault-tolerant extension of distributedsimulation algorithm, and dual global service agents. With the prevalent of the Internet and Web, it is necessary to provide ways to interact withthe simulation applications remotely, such as controlling the process of simulation and showingthe results of simulation via navigators.
