  mean vector
We also establish a version of the CLT with random matrix normalization which allows us to construct approximate confidence intervals for the unknown mean vector.
      
The proposed method only estimates the mean vector and covariance matrix of the high-resolution multispectral (MS) images, instead of assuming the joint distribution between the panchromatic (PAN) image and low-resolution multispectral image.
      
Change-point detection of mean vector or covariance matrix shifts using multivariate individual observations
      
A preliminary control chart is given for detecting a shift in the mean vector, the covariance matrix, or both, when multivariate individual observations are available.
      
When a shift is detected, the plotted statistic is divided into a part due to the shift in the sample mean vector and another part attributable to a shift in the sample covariance matrix.

Most of the current procedures for multiple factor analysis are concerned with complete observations, and to obtain MLE by the ordinary Flettcher-Powell method or Newton-Raphson method. From the practical point of view, however, usual observations contain missing values and occasionally restriction exist among parameters in multiple factor model. The present paper is to propose a systematic procedure to obtain the maximum likelihood estimation (MLE) under the general necessity described above. The procedure...

Most of the current procedures for multiple factor analysis are concerned with complete observations, and to obtain MLE by the ordinary Flettcher-Powell method or Newton-Raphson method. From the practical point of view, however, usual observations contain missing values and occasionally restriction exist among parameters in multiple factor model. The present paper is to propose a systematic procedure to obtain the maximum likelihood estimation (MLE) under the general necessity described above. The procedure is fundamentally based on Dempster-Laird-Rubin's EM algorithm, and gives an excellent property to obtain iteratively and surely the MLE with monotonous approach from initial values.

本文将EM方法应用于含有欠测数据的因子分析的最大似然估计问题,利用EM法统一处理了为保证估计唯一性的种种条件下的最大似然估计问题,得到了相当统一的迭代算法。这种处理方法可以简单地将根据欠测样本估计正态分布的期望向量与协方差阵的问题及回归问题作为其特例。从而使建立具有泛用性的计算程序成为可能。

Let Y1, Y2…, Yn have i.i.d, where is a known real matrix,are unknown parameters. In this paper, we discuss the admissible condition of anestimator common mean parametric vector under vector loss function. The necessary and sufficientcondition that a linear eStimator L1Y1 + L2Y2 +… + LnYn of Sβ is admissible in linear estimatorclass is also obtained.Keywords: veCtor loss function; admissibility and linear estimator

A new algorithm for the direct allocation method named "adjacent facets searching algorithm "was presented to solving the three-objective constrained control allocation problem.The key problem of direct allocation method is to determine the intersection of the desired objective vector with the convex hull of the attainable moments set(AMS).Instead of searching all the boundary of the AMS,the algorithm proposed start from a facet in the boundary of the AMS,searching the adjacent facets one by one,until the facet with which the desired objective intersected was founded.The algorithm relaxed the restriction assumed in the original method that any three columns of the controls effectiveness matrix are linearly independent,and returns optimal solutions in any cases.The high precision and the ability of real time application were validated.Simulation result shows the effectiveness of the algorithm,when applying in the flight control system of an aircraft with multiple control surfaces.

对于三维目标的受限控制量分配问题,给出了直接控制分配方案的一种新的算法———相邻面搜索算法.直接控制分配方法的关键是找到期望目标向量与目标可达集合外表面的交点.该算法不需要确定目标可达集的所有表面,而是由目标可达集表面一个面出发,逐步确定相邻的面,直到找到与期望向量相交的面.算法放宽了原算法中控制效率矩阵任意三列线性无关的条件,并且能够在各种情况下得到最优分配结果.经验证,算法满足精确性与实时性要求.该算法的有效性在某多操纵面飞机的飞行控制系统仿真中得到了验证.
