摘要： 判别分析是根据所研究的个体的观测指标来推断该个体所属类型的一种统计方法,对已知分类的数据建立由数值指标构成的分类规则，然后把这样的规则应用到未知分类的样本去分类。该文以判别分析中的线形判别分析和Mahalanobis距离判别分析作理论依据, 提出一种数据分析库的设计和实施方案,该系统在数据分析方面的研究和应用中有一定的特色。

Abstract: Discriminant analysis is a statistical method used to identify the unit according to its type. The analysis contributes guideline of classified data to the rules, then uses the rules to classify the unit unknown. In this paper, the design and implentation of discriminant analysis-based data analysis library system is discussed. This system adopts the linear discriminant analysis and Mahalanobis distance discriminant analysis and has some value in the research and application of data analysis.
