In simulation study ,survival distribution ,censored distribution and censored proportion are important factors .This article introduces the general steps to simulate survival data which includes censored data .At the same time ,the simulation methods of survival time ,censored time and survival data are dis-cussed with SAS programs .%生存分布、删失分布、删失比例等因素是生存数据模拟需考虑的重要因素。按含删失的生存数据产生的一般步骤,分别探讨了生存时间生成,删失时间生成,以及删失比例大小设置为不同数值时,生存数据模拟生成的方法,并辅以SAS程序说明。
