判别分析

With the sample of the newest financial data of the company issued by the ST in 2006-2007, and the sample of the normal company at the same time, the study takes example for the financial data released by the listed companies and selects the ROE（Rate of Return on Common Stockholders'Equity ）, the sales net profit rate and the current ratio of three financial targets, which are discriminated and analysed with univariate method.

摘 要：本文以我国上市公司为研究对象，通过对上市公司财务危机的定义、财务危机与企业失败的关系、以及财务危机预警的研究，以2006-2007年上市公司最新一次被ST发布的财务数据为估计样本，以同期的正常公司为配对样本，选取净资产收益率、销售净利率和流动比率三个财务指标，运用单变量方法进行判别分析。

In the research, 28 characters including energy, informationization measure, fractal dimension, hue, cb, color moment, disease spot area, rotundity, figure factor, and others were extracted, and four approximate features were selected from 28 primordial features. The results indicated that the precision of the three kinds of maize disease recognition was higher than 90%.

研究中提取了墒、相关信息测度、分形维数、H值、Cb值、颜色矩、病斑面积、圆度、形状因子等28个特征向量，利用遗传算法优选出H值、颜色矩、病斑面积、形状因子等4个独立、稳定性好、分类能力强的特征向量，应用费歇尔判别分析法识别病害，准确率达到90%以上。

Moreover, the block of texture was selected on the basis of the central line of crop row. The co-occurrence matrixes of the H color space that was quantified 8 levels were computed. Based on that, five texture parameters were extracted. Then, the K-means clustering method was used to recognize weeds within crop rows.

然后，以作物行中心为基准来选取纹理块，计算量化级数为8级的H颜色空间的共生矩阵，提取5个纹理特征参数，利用K均值聚类法判别分析各块的类别来识别行内杂草。

Studies are empirically carried out, and prefer classification tree to statistical methods in classification accuracy and variable selection.

结果表明递归分类树在变量选择和分类方面的效果好于判别分析方法。

This approach first aligned 3D faces based on non-uniform mesh re-sampling which result the uniform number of vertex and topology structure and kept in a vector. Second, we changed the vector to the matrix by division and overlap, and then 2DLDA suggests a feature selection strategy to select the most discriminative features from the corner.

该算法首先使用基于非均匀网格重采样的方法对所有三维人脸做规格化处理，使三维人脸具有统一的点数和拓扑结构；其次，以先分段、再重叠的形式将原本一维向量表示组织为二维矩阵表示，然后使用二维线性判别分析方法(2DLDA)对获得的数据进行特征抽取。

Experimental results illustrate that the combination of LBP and Fisher discrimiant analysis is better than other methods. The performance after fusing facial depth image and grayscale images is better than that of unimodal ones.

实验结果表明LBP和Fisher判别分析方法的结合要优于其它方法，在其融合人脸深度图像和灰度图像后，性能较单一信息有进一步的提升。

Based on the results of Fisher linear discrimination analysis,the first principal component score spectrum of three-dimensional fluorescence spectrum is chosen as the identification characteristic spectrum for Bacillariophyta and Pyrrophyta,and the phytopla...

根据Fisher判别分析结果，选用三维荧光光谱的第一主成分得分谱作为硅藻和甲藻的识别特征谱，建立了浮游植物荧光特征谱库。

Morphological differences among two Eriocheir japonicus populations collected from Suifen River and Hepu River and two Eriocheir sinensis populations from Changjiang and Liaohe River were studied based on cluster analyzing and discriminal analyzing on 17 morphological characters , and the hybrids of Eriocheir sinensis× Eriocheir japonicus was also researched as an assistant subject.

选取合浦水系和绥芬河水系的日本绒螯蟹与长江水系和辽河水系的中华绒螯蟹4个绒螯蟹种群，以辽河水系绒螯蟹与绥芬河水系绒螯蟹杂交后代为辅助研究对象，对它们的17个外部形态特征分别进行聚类和判别分析。
