摘要
线性的相关分析方法只能处理线性相关与否的问题,它无法用来了解是否存在非线性的相关.本文中我们提出一种近似的相关分析方法——Fuzzy 相关分析法,它主要可用于建立 Fuzzy 模型时对 Fuzzy 变量间的相关程度加以度量.此法的原理建立在 Fuzzy 规则模型的基础之上,数学上并不严格.但大量的算例表明,这种 Fuzzy 相关分析方法有相当的实用价值.
Linear correlation analysis approach can't be used to determine whether nonlinear correlation existsbut to solve linear correlated or noncorrelated problems.This article presents an approximate algorithm—Fuzzy correlation analysis approach,which can be mainly used to measure the correlation levels betweenFuzzy variants in Fuzzy modelling.This algorithm is based on the model of Fuzzy laws and is notmathematically strict;however,plenty of examples show it is good and practical.
