Extending the Archimedean Copula Methodology to Model Multivariate Survival Data Grouped in Clusters of Variable Size
扩展阿基米德 Copula 方法以建模簇规模不等的多元生存数据
Summary For the analysis of clustered survival data, two different types of model that take the association into account are commonly used: frailty models and copula models. Frailty models assume that, conditionally on a frailty term for each cluster, the hazard functions of individuals within that cluster are independent. These unknown frailty terms with their imposed distribution are used to express the association between the different individuals in a cluster. Copula…
