论文摘要
提出了有关指定协变量或协变量组的比例危害假设的测试。替代方案的类别很广:在不同值的协变量下,对数危险的速率可能会跨越,接近,消失。数据可能是正确的审查。得出了测试统计量的极限分布。测试的力量与接近替代方案有关。考虑实际数据示例。
Tests for proportional hazards assumption concerning specified covariates or groups of covariates are proposed. The class of alternatives is wide: log-hazard rates under different values of covariates may cross, approach, go away. The data may be right censored. The limit distribution of the test statistic is derived. Power of the test against approaching alternatives is given. Real data examples are considered.
