我们为Cox比例风险模型拟合样本调查数据开发了一种类似似然比检验的方法。我们着眼于计算渐近分布的方法和改进小样本性能的方法。这些方法用来自国家健康和营养检查调查和一项分层案例研究的数据举例说明。版权所有：John Wiley & Sons， Ltd。
We develop an analog of the likelihood ratio test for Cox proportional hazards models fitted to sample survey data. We look at methods for computing the asymptotic distribution and at ways of improving the small-sample performance. The methods are illustrated with examples using data from the National Health and Nutrition Examination Survey and from a stratified casecohort study. Copyright (c) 2012 John Wiley & Sons, Ltd.
