A least-absolutes approach to multi-dimentional fuzzy regression modellig is introduced and investigated for the case of crisp input/fuzzy output data, by using a generalized Hausdorff metric.
A comparative study, based on three well-known goodness-of-fit indices and three data set, including a real agricultural data set, indicate the performance of the proposed approach with respect to some common approaches to fuzzy regression modelling.
Keywords: Imprecise data; Fuzzy regression; Hausdorff metric; Least-absolutes method
