Statistical Inference of a Competing Risks Model with Modified Weibull Distributions
Abstract Statistical inferences of the parameters included in a competing risks model are presented. It is assumed here that the causes of failures may occur at times that follow modified Weibull distributions. The case of Weibull distributions can be derived as special case of the problem studied in this paper. The maximum likelihood procedure is used to get the point estimations and asymptoti...
متن کاملOn progressively censored competing risks data for Weibull distributions
In survival analysis, or in reliability study, an investigator is often interested in the assessment of a specific risk in the presence of other risk factors. It is well known as the competing risks problem in statistical literature. Moreover, censoring is inevitable in any life testing or reliability study. In this paper, we consider a very general censoring scheme, namely a progressive censor...
متن کاملParametric Estimation in a Recurrent Competing Risks Model
A resource-efficient approach to making inferences about the distributional properties of the failure times in a competing risks setting is presented. Efficiency is gained by observing recurrences of the compet- ing risks over a random monitoring period. The resulting model is called the recurrent competing risks model (RCRM) and is coupled with two repair strategies whenever the system fails. ...
متن کاملEstimation of Weibull Parameters for Grouped Data with Competing Risks
When experimental units, on a cross-sectional or a longitudinal study, are followed up periodically, the event(s) of interest may only be known to have occurred between two dates of follow-up. In this case data are usually presented in form of counts of events in each of the follow-up intervals (grouped data). Furthermore, in studies of survival, subjects may be at risk of failure due to more t...
متن کاملAnalysis of Progressive Type-II Censoring in the Weibull Model for Competing Risks Data with Binomial Removals
In reliability and survival analysis, the cause of failure/death of items/subjects can be attributed to more than one source. It is well known as the competing risks problem in statistical literature. In this paper, we assume that the lifetime of each unit which fails due to a different cause of failure, follows a Weibull distribution with different parameters. It is further assumed that in the...
