The objective of hazards (lifetime) analysis is to advance and promote statistical science in the various applied fields that deal with lifetime (survival) data including: actuarial science and reliability engineering. The lifetime data analysis provides special techniques that are required to compare the risks for failure. Bayesian semi-parametric methods have been applied to survival analysis...
Asymptotic normality of corrected estimator in Cox proportional hazards model with measurement error
Most existing copula models for dependent censoring in the literature assume that parameter defining is known. However, prior knowledge on this dependence often unavailable. In article we propose a novel model under which does not need to be The based parametric relation between survival time (T) and (C), whereas marginal distributions of T C follow semiparametric Cox proportional hazards model...
BACKGROUND Polytomous logistic regression models are commonly used in case-control studies of cancer to directly compare the risks associated with an exposure variable across multiple cancer subtypes. However, the validity, accuracy, and efficiency of this approach for prospective cohort studies have not been formally evaluated. METHODS We investigated the performance of the polytomous logist...
