nonsingular matrix：非奇异阵

保证OLS解的存在性,唯一性,及求出的解是使得残差项平和(SSE)最小的解,证明的方法是通过矩阵X'X是非奇异阵(nonsingular matrix)及 正定(positive definite)来说明非齐次线性方程系统(heterogeneity linear equations system)的解的存在性及唯一性,

nonsingular：非奇异

我们假定V 是一个非奇异(nonsingular)阵,这在经济一个正定(positive definite)阵,即对于任何非0 的向量a ,都有 0T >Vaa . 因此整个资产局最优(global optimum)解,而且仅仅考虑一阶条件就足够了. 详细讨论参见第七章中的有关内容.
