Regression Models for Lifetime Data: An Overview

open access: yesStats, 2022
Two methods dominate the regression analysis of time-to-event data: the accelerated failure time model and the proportional hazards model. Broadly speaking, these predominate in reliability modelling and biomedical applications, respectively.

A New Approach to Proportional Hazards Modeling for Estimating Customer Lifetime Value [PDF]

open access: yesarXiv, 2022
Estimating customer lifetime value (CLV or LTV) is extremely important for making better business decisions. The proposed flexible proportional hazards model allows an estimation of lifetime value in contractual settings. This approach takes advantage of a churn model, which is assumed to be available.

Model-based Prediction of Length of Stay for Rehabilitating Stroke Patients

open access: yesJournal of the Formosan Medical Association, 2009
Accurate length-of-stay (LOS) estimates have an impact on medical costs for stroke patients. Most studies have reported only descriptive sample means or have provided linear-model-based estimates for LOS.

Associations among apolipoproteins, oxidized high-density lipoprotein and cardiovascular events in patients on hemodialysis. [PDF]

open access: yesPLoS ONE, 2017
Apolipoproteins are associated with survival among patients on hemodialysis (HD), but these associations might be influenced by dysfunctional (oxidized) high-density lipoprotein (HDL).

Coach Turnover in Top Professional Brazilian Football Championship: A Multilevel Survival Analysis

open access: yesFrontiers in Psychology, 2019
In this study, we examined the probability of coaches’ survival in the top Brazilian professional football championship considering variation across the competitive seasons between 2012 and 2017, considering a multilevel framework.

A simulation study of the estimation quality in the double-Cox model with shared frailty for non-proportional hazards survival analysis [PDF]

open access: yesarXiv, 2022
The Cox regression, a semi-parametric method of survival analysis, is extremely popular in biomedical applications. The proportional hazards assumption is a key requirement in the Cox model. To accommodate non-proportional hazards, we propose to parameterise the shape parameter of the baseline hazard function using the additional, separate Cox ...

A Class of Functional Methods for Error-Contaminated Survival Data Under Additive Hazards Models with Replicate Measurements

open access: yes, 2016
Covariate measurement error has attracted extensive interest in survival analysis. Since Prentice, a large number of inference methods have been developed to handle error-prone data that are modulated with proportional hazards models.

Conditional Akaike information under generalized linear and proportional hazards mixed models.

open access: yesBiometrika, 2011
We study model selection for clustered data, when the focus is on cluster specific inference. Such data are often modelled using random effects, and conditional Akaike information was proposed in Vaida & Blanchard (2005) and used to derive an information

A novel 14-gene signature for overall survival in lung adenocarcinoma based on the Bayesian hierarchical Cox proportional hazards model

open access: yesScientific Reports, 2022
There have been few investigations of cancer prognosis models based on Bayesian hierarchical models. In this study, we used a novel Bayesian method to screen mRNAs and estimate the effects of mRNAs on the prognosis of patients with lung adenocarcinoma ...

Effect of regional medical disparities on complications in patients with hypertension: Cox’s proportional hazard models

open access: yesFrontiers in Medicine, 2023
ObjectiveComplications associated with hypertension can be alleviated by providing necessary medical services. However, there may be disparities in their provision depending on regional differences.
