Statistical analysis and application of competing risks model with regression

open access: yesCroatian Operational Research Review, 2019
The paper deals with the methods of statistical analysis of dependent competing risks in the presence of covariates. The problem of identification of marginal and joint distributions of competing random variables is recalled and certain ...

Weighted Competing Risks Quantile Regression Models and Variable Selection

open access: yesMathematics, 2023
The proportional subdistribution hazards (PSH) model is popularly used to deal with competing risks data. Censored quantile regression provides an important supplement as well as variable selection methods due to large numbers of irrelevant covariates in

Statistical analysis of dependent competing risks model in constant stress accelerated life testing with progressive censoring based on copula function

open access: yesStatistical Theory and Related Fields, 2018
In this paper, we consider the statistical analysis for the dependent competing risks model in the constant stress accelerated life testing with Type-II progressive censoring. It is focused on two competing risks from Lomax distribution.

Understanding competing risks: a simulation point of view

open access: yesBMC Medical Research Methodology, 2011
Background Competing risks methodology allows for an event-specific analysis of the single components of composite time-to-event endpoints. A key feature of competing risks is that there are as many hazards as there are competing risks.

Semi-Competing Risks on A Trivariate Weibull Survival Model

open access: yes, 2008
A setting of a trivairate survival function using semi-competing risks concept is proposed. The Stanford Heart Transplant data is reanalyzed using a trivariate Weibull distribution model with the proposed survival ...

Modelling competing risks data by a bivariate model with singularity originating from a shock model using the Lehmann family of distributions

open access: yesResearch in Statistics
In this article, a general family of bivariate distributions is used to model competing risks data with dependent causes. The general structure of competing risks data considered here includes ties.

Dipolar Tree Ensemble With and Without Adjustment to Competing Risks: Application to Medical Data

open access: yesStudies in Logic, Grammar and Rhetoric, 2013
The analysis of survival data often aims at the prediction of failure time distribution. In cases of competing risk events, the time distributions of more than one failure are under investigation.

Competing risks to breast cancer mortality in Catalonia

open access: yesBMC Cancer, 2008
Background Breast cancer mortality has experienced important changes over the last century. Breast cancer occurs in the presence of other competing risks which can influence breast cancer incidence and mortality trends. The aim of the present work is: 1)

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...
