一、问题的提出在体育统计中,回归是做客观定量分析的重要方法,尤其对于多因子的挑选,逐步回归标志着回归方法的理论和计算日臻完备;所以,在众多的统计方法中,回归分析一直是人们常用的数理统计方法之一。但是,在体育实践活动中,用回归分析经常会遇到这样几个问题不易解决: 1、逐步回归分析只能解决变量间呈线性关系的问题,但对于众多的变量呈非线性关系 First, the issue put forward in sports statistics, regression is to do an objective quantitative analysis of the important methods, especially for the selection of multiple factors, the gradual regression of the regression method marks the theory and calculation is complete; So, in many statistical methods, regression Analysis has always been one of the commonly used mathematical statistics. However, in the practice of sports, it is not easy to solve such problems by using regression analysis: 1. Stepwise regression analysis can only solve the problem of linear relationship between variables, but it has a nonlinear relationship with many variables
