Semiparametric Accelerated Failure Time Modeling for Clustered Failure Times From Stratified Sampling
分层抽样下聚类失效时间的半参数加速失效时间建模
Clustered failure times often arise from studies with stratified sampling designs where it is desired to reduce both cost and sampling error. Semiparametric accelerated failure time (AFT) models have not been used as frequently as Cox relative risk models in such settings due to lack of efficient and reliable computing routines for inferences. The challenge roots in the nonsmoothness of the rank-based estimating functions, and for clustered data, the asymptotic properties of…
