| Summary: | The purpose of this article was to introduce the score test and the SAS implementation. Concretely， there were five common forms of the score test statistics， namely the general score test statistic，the robust score test statistic，the residual score test statistic，the generalized score test statistic，and the Lagrange multiplier test statistic. The score test was mainly used in the following three situations， namely， testing whether part or all of the regression coefficients were 0， testing whether a single effect was not in the regression model，and testing whether the parallel line hypothesis was established. The paper used two examples and the SAS software to realize the various score tests mentioned above， and focused on explaining the output results related to the score tests. |
