Mathematical Modeling of Operational Reliability of Mine Lifting Equipment Based on Censored Data

Mathematics
In this study, a comprehensive mathematical method for modeling the operational reliability of mine hoisting equipment under conditions of incomplete and heavily censored data is developed.

Bayesian robust symmetric regression for medical data with heavy-tailed errors and censoring.

PLoS ONE
Bayesian symmetric regression offers a principled framework for modeling data characterized by heavy-tailed errors and censoring, both of which are frequently encountered in medical research. Classical regression methods often yield unreliable results in

Informative Censoring in CDK4/6 Inhibitor Adjuvant Therapy for Early Breast Cancer: A Sensitivity Analysis of Invasive Disease-Free Survival in the monarchE Trial

Epidemiology, Biostatistics and Public Health
INTRODUCTION The estimation of survival curves and hazard functions relies on the assumption of non-informative censoring—that is, the censoring time for an individual provides no further information about that person’s likelihood of survival at a ...

Regression methods for cost-effectiveness analysis with censored data

, 2004
A system of seemingly unrelated regression equations is proposed for prognostic factor adjustment and subgroup analysis when comparing two groups in a cost-effectiveness analysis with censored data. Because of the induced dependent censoring on costs and

Semiparametric Analysis of Clustered Interval-Censored Survival Data with a Cure Fraction

, 2014
A generalization of the semiparametric Cox's proportional hazards model by means of a random effect or frailty approach to accommodate clustered survival data with a cure fraction is considered.

Sensitivity models for missing covariates in the analysis of survival data from multiple surveys [PDF]

, 2007
Using individual patient data from five independent surveys, we evaluate regional variations in survival in cerebral palsy. The influence of four important variables measuring disability, which are only partially observed for many cases, are analysed ...

Smoothed Weighted Quantile Regression for Censored Data in Survival Analysis

Axioms
In this study, we propose a smoothed weighted quantile regression (SWQR), which combines convolution smoothing with a weighted framework to address the limitations.

p3state.msm: Analyzing Survival Data from an Illness-Death Model [PDF]

In longitudinal studies of disease, patients can experience several events across a followup period. Analysis of such studies can be successfully performed by multi-state models.

A Method of Nonparametric Survival Analysis for Doubly Censored Data.

, 1981
This thesis presents a new model and method of analysis for survival time data which can be right and /or left censored. Most of the recent work in survival analysis has been concerned with association between certain covariates, X, and time S ...
