对体育科研中多元线性回归模型变量间关系的探析

Analysis on Variable Relations of Multivate Linear Regression Model in P. E. Scientific Research

本文针对回归分析在体育科研中存在的几个与变量有关的典型问题进行分析,指出建立有价值回归模型的关键在于认清回归分析中两类变量问的关系,而认清变量间关系必须深入理解回归分析的实质。本文从2个不同的角度剖析回归分析的基本思想和实质,以期广大体育科研工作者能够正确的使用多元线性回归模型。

This paper based on some type questions about variable relation in regression analysis in P E. research and put forward that recognizing two types of variable relations is key segment for building a worth model of regression. Howevre, the author thinks that catching on the substance of regression aim to recognizing variable relations. Analysis basic idea and substance of regression to help researcher using the model correctly.
