Statistical analysis of dependent competing risks model from Gompertz distribution under progressively hybrid censoring
Previous studies have mostly considered the competing risks to be independent even when the interpretation of the failure modes implies dependency. This paper studies the dependent competing risks model from Gompertz distribution under Type-I progressively hybrid censoring scheme. We derive the maximum likelihood estimations of the model parameters, and then the asymptotic likelihood theory and...
متن کاملCONSTANT STRESS ACCELERATED LIFE TESTING DESIGNWITH TYPE-II CENSORING SCHEME FOR PARETO DISTRIBUTION USING GEOMETRIC PROCESS
In many of the studies concerning Accelerated life testing (ALT), the log linear function between life and stress which is just a simple re-parameterization of the original parameter of the life distribution is used to obtain the estimates of original parameters but from the statistical point of view, it is preferable to work with the original parameters instead of developing inferences for the...
متن کاملTracking Interval for Type II Hybrid Censoring Scheme
The purpose of this paper is to obtain the tracking interval for difference of expected Kullback-Leibler risks of two models under Type II hybrid censoring scheme. This interval helps us to evaluate proposed models in comparison with each other. We drive a statistic which tracks the difference of expected Kullback–Leibler risks between maximum likelihood estimators of the distribution in two diff...
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...
متن کاملInference for a step-stress model with competing risks from the GE distribution under Type-I censoring
In reliability analysis, accelerated life-testing allows gradual increment of stress levels on test units during an experiment. In a special class of accelerated life tests known as step-stress tests, the stress levels increase discretely at pre-fixed time points, allowing the experimenter to obtain information on the lifetime parameters more quickly than under normal operating conditions. More...
