Interval-Censored Regression with Non-Proportional Hazards with Applications

Stats, 2023
Proportional hazards models and, in some situations, accelerated failure time models, are not suitable for analyzing data when the failure ratio between two individuals is not constant. We present a Weibull accelerated failure time model with covariables

Load Redistribution-based Reliability Enhancement for Storage Area Networks [PDF]

International Journal of Mathematical, Engineering and Management Sciences, 2023
Storage area networks (SANs) are one of the prevalent reliable data storage solutions. However, cascading failures triggered by data overloading have become a major threat to SANs, preventing the desired quality of service from being delivered to users ...

Kernel based methods for accelerated failure time model with ultra-high dimensional data

BMC Bioinformatics, 2010
Background Most genomic data have ultra-high dimensions with more than 10,000 genes (probes). Regularization methods with L1 and Lp penalty have been extensively studied in survival analysis with high-dimensional genomic data.

Analysis of Life Insurance Contract Cancellations Using the Accelerated Failure Time Model [PDF]

Statistika: Statistics and Economy Journal
The aim of this paper is to analyse the cancellation of life insurance contracts on death using an accelerated failure time (AFT) model. The study focuses on identifying risk factors that influence the time to cancellation, with the objective of ...

Goodness-of-fit test for the accelerated failure time model based on martingale residuals [PDF]

, 2013
summary:The Accelerated Failure Time model presents a way to easily describe survival regression data. It is assumed that each observed unit ages internally faster or slower, depending on the covariate values.

Semiparametric estimation for accelerated failure time mixture cure model allowing non-curable competing risk

Statistical Theory and Related Fields, 2020
The mixture cure model is the most popular model used to analyse the major event with a potential cure fraction. But in the real world there may exist a potential risk from other non-curable competing events.

Examining Risk Factors Accelerating Time-to-Chronic Obstructive Pulmonary Disease (COPD) Diagnosis among Asthma Patients

COPD, 2022
Asthma patients may have an increased risk for diagnosis of chronic obstructive pulmonary disease (COPD). However, risk factors accelerating time-to-COPD diagnosis are unclear.
