Abstract: | Two dimensional Newton interpolation formula upper triangular lattice network is constructed by the Excel software through the operation method on the table. Finally, an example demonstrates how the two-dimensional discrete random variable distribution law in exponential form derived from multiple two dimensional Newton interpolation problem by using the method proposed in this paper. |
