Abstract: The paper demonstrates the existence of the optimal straight line under the minimum of weighted total least absolute deviation, and suggests the two necessary conditions that the optimal straight line should satisfy, and provides evidence for the calculation of accurate and optimal solution.
Keywords: Weighted total least absolute deviations   optimal straight line   existence   necessary conditions.
