| Abstract: | 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. |
