Q1. What have the authors contributed in "Regression analysis of competing risks data with general missing pattern in failure types" ?
In this work, the authors deal with the regression problem, in which the cause-specific hazard rates may depend on some covariates, and consider estimation of the regression coefficients and the cause-specific baseline hazards under the general missing pattern using some semi-parametric models. The authors consider two different proportional hazards type semi-parametric models for their analysis. The authors also consider an example from an animal experiment to illustrate their methodology.
