Analysis of spatial frailty models by a weighted estimating equation
PS Lin - Journal of Statistical Planning and Inference, 2012 - Elsevier
Spatially correlated survival data are frequently observed in ecological and epidemiological
studies. An assumption in the clustered survival models is inter-cluster independence, which …

Frailty modeling for spatially correlated survival data, with application to infant mortality in Minnesota
The use of survival models involving a random effect or 'frailty'term is becoming more
common. Usually the random effects are assumed to represent different clusters, and …

Analysis of clustered and interval censored data from a community‐based study in asthma
Many authors in recent years have proposed extensions of familiar survival analysis

Bias correction in the hierarchical likelihood approach to the analysis of multivariate survival data
Frailty models are useful for measuring unobserved heterogeneity in risk of failures across
clusters, providing cluster-specific risk prediction. In a frailty model, the latent frailties shared …

Dynamic survival models with spatial frailty
LS Bastos, D Gamerman - Lifetime data analysis, 2006 - Springer
In many survival studies, covariates effects are time-varying and there is presence of spatial
effects. Dynamic models can be used to cope with the variations of the effects and spatial …

A marginal likelihood approach to estimation in frailty models
KF Lam, AYC Kuk - Journal of the American Statistical Association, 1997 - Taylor & Francis
A marginal likelihood approach is proposed for estimating the parameters in a frailty model
using clustered survival data. To overcome the analytic intractability of the marginal …

Marginal analysis for clustered failure time data
SE Lu, MC Wang - Lifetime Data Analysis, 2005 - Springer
Clustered failure time data are commonly encountered in biomedical research where the

Semiparametric spatial frailty modeling for survival data based on copulas
JI Seo, Y Kim - Communications in Statistics-Simulation and …, 2022 - Taylor & Francis
In this study, we describe a frailty model for spatially correlated survival data based on the
class of Archimedean copulas in the spatial regression, assuming that counties are allowed …

Modeling spatial survival data using semiparametric frailty models
We propose a new class of semiparametric frailty models for spatially correlated survival
data. Specifically, we extend the ordinary frailty models by allowing random effects …
