Weighted Competing Risks Quantile Regression Models and Variable Selection
Mathematics, 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

Regression Analysis of Masked Competing Risks Data under Cumulative Incidence Function Framework
Austrian Journal of Statistics, 2020 In the studies that involve competing risks, somehow, masking issues might arise. That is, the cause of failure for some subjects is only known as a subset of possible causes.

Summarizing differences in cumulative incidence functions
Statistics in Medicine, 2008 AbstractThe cumulative incidence function is widely reported in competing risks studies, with group differences assessed by an extension of the log‐rank test. However, simple, interpretable summaries of group differences are not available. An adaptation of the proportional hazards model to the cumulative incidence function is often employed, but the ...

Regression Trees for Cumulative Incidence Functions
, 2020 The use of cumulative incidence functions for characterizing the risk of one type of event in the presence of others has become increasingly popular over the past decade. The problems of modeling, estimation and inference have been treated using parametric, nonparametric and semi-parametric methods.
