Prentice(1986)提出了案例 - 果园的设计,并研究了考克斯模型中回归参数的假丝孔估计器。我们得出了一类针对病例 - 霍特采样的估计方程,每个方程式取决于人口分布的不同估计器,这自然导致了简单的估计器,这些估计器改善了Prentice的假洛基氏估计量。我们还讨论了COX模型中回归参数的估计,病例对照和病例对象采样之间的等效性。
Prentice (1986) proposed the case-cohort design and studied a pseudolikelihood estimator of regression parameters in Cox's model. We derive a class of estimating equations for case-cohort sampling, each depending on a different estimator of the population distribution, which lead naturally to simple estimators that improve on Prentice's pseudolikelihood estimator. We also discuss an equivalence between case-control and case-cohort sampling in terms of the estimation of regression parameters in Cox's model.
