摘要
本文提出并研究了大型回归系统的线性估计问题,给出了实用的各种优良性标准及各种估计的奇异值函数,并对它们进行了新的分类。
In this paper we propose and study the problem of the linear estimator in the large-scale regression system. Some good criteria, singular value functions of all kinds of estimator and a new method of classification have been given, too.
