主因素分析方法及其实例

A Method of Analysis of Principal Factor and an Example of Application

主因素分析方法是多元统计方法的一个新支,它在多种学科如气象学、经济学等都有成功应用的实例,但应用于栽培学,却遇到了困难,因为不好作出明确的生物学解释。近年来,有一些解决这一难题的方法,但只限于很特殊的情况。本文应用动态分析的方法,给出了一个在一般情况下都能应用的方法,并给出了一个说明性的实例。

Principal factor analysis is a new branch of multivariatestatistical analysis.It has been successfully applied to many disciplinessuch as meteorology,economics,etc.But there are some difficulties forapplication in plant cultivation,for it is difficult to give a clear anddefinite explanation biologically.There has been some approaches to theseproblems recently,but only limited to a very few particular cases.In thispaper,a generally applicable method,with an illustrative example,is givenby the use of dynamic analysis.
