Flexible Parametric Accelerated Hazard Model: Simulation and Application to Censored Lifetime Data with Crossing Survival Curves

open access: yesMathematical and Computational Applications, 2022
This study aims to propose a flexible, fully parametric hazard-based regression model for censored time-to-event data with crossing survival curves. We call it the accelerated hazard (AH) model.

Global Bahadur Representation For NonParametric Censored Regression Quantiles and its Applications [PDF]

open access: yes, 2013
This paper is concerned with the nonparametric estimation of regression quantiles of a response variable that is randomly censored. Using results on the strong uniform convergence rate of U-processes, we derive a global Bahadur representation for a ...

Goodness-of-fit criteria for survival data [PDF]

open access: yes, 2004
The definition of an appropriate measure for goodness-of-fit in case of survival data comparable to R^2 in linear regression is difficult due to censored observations.

ANALISIS SURVIVAL DENGAN COX PROPORTIONAL HAZARD PADA KASUS DEMAM TIFOID

open access: yesMajalah Ilmiah Matematika dan Statistika, 2022
A common problem found in survival data is the presence of censored data. The length of hospitalization of Typhoid fever patients until declared cured is one of example of this data. Here, we use Cox regression model to analysis this data.

Semiparametric linear regression with censored data and stochastic regressors [PDF]

open access: yes, 1994
We propose three new estimation procedures in the linear regression model with randomly-right censored data when the distribution function of the error term is unspecified, regressors are stochastic and the distribution function of the censoring variable

ICBoost: An XGBoost-Based Unbiased Transformed Algorithm for Survival Regression

open access: yesIEEE Access
Prediction models for disease onset are critical in biomedical research and survival analysis. With machine learning methods increasingly being used to handle survival data with censoring, unbiased transformation theory offers an alternative method for ...

Survival analysis of A.C. machines in the diamond industry using the Kaplan-Meier estimator

open access: yesMATEC Web of Conferences, 2017
The article deals with the survival analysis of a.c. machines operating under the conditions of the underground mine “Mir” (Yakutia). The estimation of their survival is carried out using the Kaplan-Meier estimator.

Advanced Joint Survival Models for Evaluating Treatment Efficacy

open access: yesProceedings of the International Conference on Applied Innovations in IT
This study proposes a joint modelling framework for evaluating treatment efficacy in AIDS by integrating longitudinal and survival data. The approach addresses a key limitation in biomedical analysis by incorporating left-censored covariates into a ...

Asymmetric Randomly Censored Mortality Distribution: Bayesian Framework and Parametric Bootstrap with Application to COVID-19 Data

open access: yesJournal of Mathematics, 2022
This article investigates a survival analysis under randomly censored mortality distribution. From the perspective of frequentist, we derive the point estimations through the method of maximum likelihood estimation.
