我们提出了一种改进的对数秩检验来分析竞争风险生存数据，当某些个体的失败类型缺失时。当所有故障类型都已知时，建议的测试减少为标准的日志秩测试。该检验由部分似然产生，在半参数假设下构建了特定原因危害之间的关系。
We propose a modified log rank test for the analysis of competing risks survival data, when failure type is missing for some individuals. The proposed test reduces to a standard log rank test when all failure types are known. The test arises from a partial likelihood, constructed under semiparametric assumptions on the relationship between cause-specific hazards.
