摘要
目的探讨Buckley-James模型在生存分析中的应用。方法介绍Buckley-James模型的计算、发展以及程序的实现,用一实例比较了Buckley-James模型和Cox模型。结果在不符合比例风险的前提下,Buckley-James模型的结果要比Cox模型准确。结论Buckley-James模型有着很好的统计学特性,它是Cox模型在不满足比例风险假定时的主要替代模型之一。
Objective To explore the application of Buckley-James model in survival analysis. Methods We introduce the algorithm, development and the computer program of Buckley-James model and compare it with Cox model through a real example. Results The results of Buekley-James model is more reliable than Cox model when dissatisfying the proportional hazard assume. Conclusion Buckley-James model showed good statistical properties under usual regularity conditions, and was used as an alternative to the popular Cox model when dissatisfying the proportional hazard assume.
