| 摘 要： | 实际工作中,某个现象的发生或得到某种结果往往与某个或某些因素有关,但是这种关系又是不确定的,譬如,若用x表示某人的身高,用y表示他的体重,一般来说,当x越大时,y也倾向于越大,但由身高x并不能严格的决定体重y,只是从数据上可以看出这种趋势.回归分期就是用来研究具有这种特种变量之间的相关关系.本文详细介绍了回归分析的理论基础及其MATLAB实现方法,并通过实例分析证明了这种方法的合理性与可行性.

| Abstract: | In practical situations, the occurrence of certain phenomenon or a result obtained from certain occa- sion is probably related to certain factors. However, it＇ s might be impractical to determine the nature of this rela- tion. E.g. , x is the height of a person, and y is his weight. Usually, if x increases, y tends to increase too, but y cannot be precisely determined with x. Only there is a tendency visible with the data. Regression is utilized to solve this kind of co-relation problems. This paper introduces the basics of regression and its implementation with MATLAB. Case studies are provided to prove the rationale and feasibility of this method. |
