Hazard Change Point Estimation
In survival analysis or reliability and maintenance studies, hazard-rate function plays an important role, since it describes the instantaneous failure probability given that the individual survived or the item has not failed up to that instance. Sudden changes in the hazard function may occur due to overhauls, treatment effects or maintenance activities. A problem of statistical interest is th...
متن کاملFull and conditional likelihood approaches for hazard change-point estimation with truncated and censored data
Hazard function plays an important role in reliability and survival analysis. In some real life applications, abrupt changes in the hazard function may be observed and it is of interest to detect the location and the size of the change. Hazard models with a changepoint are considered when the observations are subject to random left truncation and right censoring. For a piecewise constant hazard...
متن کاملEstimation of Hazard Function for Right Truncated Data
This thesis centers on nonparametric inferences of the cumulative hazard function of a right truncated variable. We present three variance estimators for the Nelson-Aalen estimator of the cumulative hazard function and conduct a simulation study to investigate their performances. A close match between the sampling standard deviation and the estimated standard error is observed when an estimated...
متن کاملBayesian Analysis of Change - Point Hazard Rate
Change-point hazard rate models arise, for example, in applying \burn-in" techniques to screen defective items and in studying times until undesirable side eeects occur in clinical trials. The classical approach develops estimates of model parameters, with particular interest in the threshold or change-point parameter, but exclusively in terms of asymptotic properties. Such asymptotics can be p...
