| Abstract: | Abstract In this paper, multiple linear litting or regression (FR) problem is discussed by using weighted least absolute deviations method. It is proved that weighted absolute deviations function has the minimum, and there is a optimum FR hyperplane spaned by (m +1) observation points in (m + 1)-dimensional space. Then, Search procedure is introduced for estimating FR coefficients, some examples illustrate the effectiveness of this method. |
