判别分析

RESULTS: All the selected items were analyzed by the different statistical methods, including significance grade, discrete tendency, principal component analysis and factor analysis, cluster analysis, stepwise regression analysis, discriminatory analysis and Cronbach's alpha. Three domains, 11 facets and 50 items made up the general structure of CH-QOL.

By the discriminatory analysis, 8 variables such as psychiatric history, the diagnosies of identification, the BPRS factor 3 and 4, the Responsibility Scale factors 3, 4, and 5 were selected into the discriminatory equations. Conclusion: The responsibility of the mental disorders correlated with the sort and the severity of the disorders.

Methods Fifty pairs of fresh colorectal cancer and homologous normal tissues were genotyped with Identifiler Kit and the mutations generated in cancer tissues were determined. The mutation rates, the numbers of locus matched without identical allele (A0), 1 identical allele (A1), or 2 identical alleles (A2) and the number of total identical alleles IA(subscript n were calculated. Frequency distributions of A0, A1, A2 and IA were compared among CR-N group, unrelated individual pairs and full sibling pairs. Discrimination functions were established for individual identification from tumor tissues with discriminatory analysis.

用Identifiler系统对50对新鲜结直肠癌组织及其身源正常组织组进行STR分型，计算CR-N组中变异STR基因座及全不同基因座数(A0)、半相同基因座数(A1)、全相同基因座数(A2)和共有等位基因数IA(下标 n，比较CR-N组、无关个体对组和全同胞对组中上述参数的分布差异，通过判别分析建立判别函数。

多元分析——方法：均值向量检验，判别分析，多元方差分析，典型相关分析，聚类分析，主成分分析，因子分析。

Fisher criterion assumes that each sample has a unimodal,symmetric distribution for each class.However,when the training sample size is large and their distributions are multimodal or skewed,the definition of classical Fisher criterion can not correctly reflect the distribution of the data in the sample space,in that case,the sets of discriminant vectors are not optimal virtually.

Fisher准则函数的前提条件就是假设每类样本数据满足单峰高斯分布，即各类样本在模式空间的分布近似椭球状，但是当训练样本数据较多且呈多峰分布时，传统的Fisher准则函数并不能准确反映样本数据的分布，显然基于Fisher准则函数的线性判别分析得到的最优判别矢量集也不是最优的。

The analysis test is such a method that divides the unrehearsed objects into several types whose sample data have been achieved and establishes test according to some criteria, then tests and classifies the sample of unknown type.

摘 要 ：判别分析法是在已知研究对象分成若干类型并已取得各种类型的一批已知样品的观测数据，在此基础上根据某些准则建立判别式，然后对未知类型的样品进行判别分类。

A discriminate function, Z=0.952X_1 +0.591X_2(U1-Apgmm)–0.430X_3 was produced by multiplefactorial discrminate analysis. Z≥0 is an indication of extraction ,and Z is anindication of nonextraction on the other side.

将这些指标通过逐步判别分析得出的判别方程为：Z=0.952x_1+0.591x_2(U1-Apgmm)-0.430x_3，有助于这两种治疗方法的选择，Z≥0时，拔牙的可能性较大，Z﹤0时，不拔牙的可能性较大。

Methods Bayes discriminant analysis was used to select the significant indexes, and the discriminant diagnostic cast and quantitative diagnostic schedule were established to diagnose early oviductal pregnancy.
