Note on the Fuzzy Group in the Fuzzy Quantification Method 1

Abstract

Roles of the fuzzy group in the fuzzy quantification method 1 are studied using the linear regression model. First, relationship between the fuzzy group and linear approximation of a nonlinear model is discussed. Secondly, it is pointed out that the fuzzy group should be related to error varianves of the linear regression model, and effect of fuzzy group data on regression analysis is studied by computer simulation.
