摘要
对两个由相同指标建立的多元回归方程作比较,即对两个多元回归方程的回归系数和常数项之间的差异进行显著性检验,用指示变量可以较为全面地反映出两个多元回归方程之间的关系。
During the research process of sports training, various kinds of structure models of athletes' competitive abilities (multiple regerssion equations)have been established by reseachers in order to guide the training better. A further study of the regular pattern of these equations shows that sometimes it is necessary to make a comparison between the two multiple regerssion equations established with the same index, which means that it is necessary to test the noticeable differences between the regression coefficients and the constants of the two multiple regression equations. The indicated variable can be used to solve this problem, because it can reflect the relations between the two multiple regerssion equations in every way.
