摘要
判别分析法是根据所研究个体的观测值来构建一个综合标准用来推断个体属于已知种类中哪一类的方法.Fisher判别分析法是一种非常重要而且应用极为广泛的判别分析法.文章介绍了Fisher判别分析法的数学思想,详细阐述了在两个总体和多个总体情况下它的判别函数以及判别准则.之后通过举例说明了Fisher判别分析法在解决实际问题中的具体应用.
The method of discriminant analysis is a method that builds comprehensive standard according to individual observed value in order to distinguish individual belonging to a certain category.Fisher discriminant analysis is a very important and widely used method.The paper introduces the mathematics thought of Fisher discriminant analysis method, discriminant function and crite-rion.Then its application of specific problems is elucidated.
