According to the result, the confidence region of unknown parameters in single-index models is constructed. Finally, we consider the test of correlation and heterogeneity for hierarchical nonlinear mixed-effects models. According to Laplace approximation expansion of integrated log-quasilikelihood, a class of score test statistics is proposed. Under some very mild conditions, we prove the asymptotic distribution of the test statistics is a standard X~2-distribution. Through a Monte Carlo simulation study, the finite sample performance is examined.

最后，我们研究的第四个问题是分层非线性随机混合效应模型的相关性与异方差性检验问题，依据对数拟积分似然的Laplace近似展开提出了检验统计量，在一些正则条件下，得到了检验统计量的渐近分布是一个标准的χ~2-(来源：d7d7A65BC论文网www.abclunwen.com)分布，通过Monte Carlo模拟研究了其小样本的表现，实例验证了其实际应用。

By Monte Carlo simulation of stochastic demand, the hybrid simulation-optimization policy is brought forward to solve the model as well as the principle to select size of the sample. Benders decomposition algorithm and its accelerated technique are presented to solve the deterministic equivalent of primal problem.

In view of disadvantages in present defect reconstruction methods,such as over-long time or excessive need for training samples,a new defect reconstruction method based on similar model and genetic algorithm was investigated as follows:similar model between non-axisymetric defect and axisymetric defect was represented,and proportionality factor was deduced by skin depth equation.

针对以往缺陷重构方法中普遍存在的计算时间长或需要大量训练样本的缺点，提出一种基于相似模型和遗传算法的缺陷快速重构方法，分析非轴对称缺陷与轴对称缺陷之间存在的相似模型，并利用集肤深度公式推导出两者之间的缩比因子，从而将耗时巨大的缺陷重构问题转换为二维轴对称情况下的计算问题；同时为进一步缩短重构时间，提出一种加快遗传算法收敛速度的方法。

One was that research objects were ruleless and dishevelled. Another was that research target was reducing Ommission Error of change parcel. The Distance Discriminate Analysis was meliorated in the paper to get better recognizing effect. One was turning the question of change parcel to the question of standard land type. Another was making strict regulation. This improved Distance Discriminate Analysis is not only visual and briefness, but also easy operational.

在设计变化地块识别的判决函数时，本文针对变化地块识别工作的特殊性：1、以无规律性、无集群性的变更地块为研究对象；2、以降低变更地块的漏判率为目标，对距离判别法做了如下改良：1、将无规律、无集群性的变更地块识别问题转化为有规律、有集群性的地类识别问题；2、严格判类规则(将落入误判高发区的待测样本视为变更地块)，以减少变更地块的漏判。

However,for the large dimensional data.the sample covariance matrix is not a good estimator of the population counterpart.Many methods of parametric estimations and tests for multivariate statistical problems can not be simply used to deal with large dimensional data.

但是由于经典的大样本理论都是假定维数很小是固定的，故而经典极限理论并不适宜解决大维随机数据问题，很多多元问题的模型参数估计、模型检验的统计量已有的结果对大维海量数据并不能平凡推广。

The SVM has the basis limited sample training to obtain good exude ability,and it\'s an general learning machine,it maps the original space into high dimensional characteristic space,makes the original classified question become a linear separable question in the characteristic space.

支持向量机具有依据有限样本训练获得良好的泛化能力，并且是一个通用的学习机，它将原空间映射到一个高维的特征空间里，使原分类问题在特征空间里成为一个线性可分的问题。

In contrast to the present algorithm which is based on the modification of connecting weights in between neurons of different layers, the new learning method adjust the deviation and slope parameters of the Sigmoid function.
