ABSTRACT
The purpose of the paper was to introduce the three special tests of the survival data and the SAS implementation. Specifically, it was the multiple comparisons, the trend test and the covariate test of the survival data. The multiple comparisons involved two situations: "the pairwise comparison" and "the comparison with control group". In the trend test, it involved two algorithms: "the log-rank test" and "the Wilcoxon test". In the covariate test, it involved "the single covariate test method" and "the multi-covariate test method of adding one covariate step by step". With the help of the SAS software and based on an example, this article implemented the three special tests mentioned above, explained the output results, and made statistical and professional conclusions.
