两组变量之间的回归

研究问题
如何将 Hotelling 关于两组变量关系的分析方法用于实际统计问题,并改善数学表述、数值计算与结果解释的可理解性?
方法与思路
作者拟将 Hotelling 的两组变量分析方法应用于两类问题,并以较简明的表述展开分析,比原论文更详细地讨论数值计算。
材料陈述的贡献
摘要所述贡献主要是应用展示与方法讲解:以两类问题说明既有方法的用途,并简化分析表述、增加数值计算细节。
阅读关注点
核对两类应用的变量定义、分析目标与结果解释,阅读具体计算程序及其所需条件,并分辨哪些内容来自既有方法。
阅读边界
摘要未说明两类问题的具体内容、计算算法或新的理论结果;不能据此断言提出新估计量、改进识别或适用于特定经济领域。

原文摘要

PROFESSOR HOTELLING'S PAPER, Relations between Two Sets of Variates,'l should be widely known and his method used by practical statisticians. Yet, few practical statisticians seem to know of the paper, and perhaps those few are inclined to regard it as a mathematical curiosity rather than an important and useful method of analyzing concrete problems. This may be due to two reasons: first, that Hotelling's paper makes use of rather complicated mathematics and does not spell out in detail the methods of numerical computation; and, second, that although the paper applied the methods to two sets of statistical data, the major emphasis is on mathematical theory, and only rather incidental consideration is given to the meaning of the results obtained in actual statistical work. This paper will try to do two things: first, and most important, it will apply these methods to two different kinds of problems in the hope that this will suggest other practical applications; second, it will develop the methods of analysis in somewhat simpler terms, and discuss numerical computation in greater detail than Hotelling's paper.
