Extended Fuzzy Linear Models and Least Squares


Least squares regression of the fuzzy linear model is extended to overcome and interpret the occurrence of negative spreads 2]. The idea is to introduce best t diierence models which exploit both the Hukuhara diierence and the L 2 ?metric distance. The fuzzy models use LR?fuzzy numbers. Fitted models are compared by using the coeecient of determination, in… (More)
