DOI: 10.1002/sim.7361
Abstract: Interval-censored failure-time data arise when subjects are examined or observed periodically such that the failure time of interest is not examined exactly but only known to be bracketed between two adjacent observation times. The commonly… read more here.

DOI: 10.1002/sim.7538
Abstract: Interval-censored failure time data occur in many areas, especially in medical follow-up studies such as clinical trials, and in consequence, many methods have been developed for the problem. However, most of the existing approaches cannot… read more here.

DOI: 10.1002/sim.7809
Abstract: Missing covariates often occur in biomedical studies with survival outcomes. Multiple imputation via chained equations (MICE) is a semi-parametric and flexible approach that imputes multivariate data by a series of conditional models, one for each… read more here.

DOI: 10.1002/sim.8318
Abstract: A framework is proposed for the joint modeling of life history and loss to follow-up (LTF) processes in cohort studies. This framework provides a basis for discussing independence conditions for LTF and censoring and examining… read more here.

DOI: 10.1007/s11749-018-0601-7
Abstract: Accelerated failure time (AFT) model is a useful semi-parametric model under right censoring, which is an alternative to the commonly used proportional hazards model. Making statistical inference for the AFT model has attracted considerable attention.… read more here.

DOI: 10.1016/j.applthermaleng.2017.08.141
Abstract: Abstract Gypsum board assemblies are important in preventing spread of flame and hot smoke, keeping escape routes available, and extending evacuation time. In general, heavier assemblies are expected to provide a higher degree of fire… read more here.

Abstract: Using positron emission tomography (PET)-derived amyloid and tau measurements from 1,495 participants, we explore the evolution of these values over time via an accelerated failure time (AFT) model. The AFT model assumes a shared pattern… read more here.

Abstract: A subcritical load on a disordered material can induce creep damage. The creep rate in this case exhibits three temporal regimes viz. an initial decelerating regime followed by a steady-state regime and a stage of… read more here.

DOI: 10.1080/00949655.2016.1222611
Abstract: ABSTRACT A nested case–control (NCC) study is an efficient cohort-sampling design in which a subset of controls are sampled from the risk set at each event time. Since covariate measurements are taken only for the… read more here.

Abstract: Accelerated Failure Time (AFT) models are viable alternatives to the Cox proportional hazard model, where failure times are explicitly modelled with respect to covariates. A major problem with parametric AFT models in practice is that… read more here.
