摘要
在Excel软件中通过表上作业法得到了上三角格点网的二元Newton插值公式.最后,用一个例子演示了如何将二维离散型随机变量分布律派生出多个二元Newton插值问题后利用本文提出的方法构造出二维离散型随机变量分布律的幂指形式.
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.
