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.

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.
