Abstract: 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.
