FUZZY LEAST SQUARE MODEL SENSITIVITY TO OUTLIERS
Possibilistic model has been very successful when dealing with fuzzy regression, but has limitations with respect to its sensitivity to outliers. In this paper, we use the fuzzy least squares to detect outliers and examined their influence. Using the basic idea underlying outliers’ detection in fuzzy regression model, it is examined that the outliers exert minor influence on the model.
