Two Methods to Estimate the Change Points of a Bathtub Curve
The failure rate function of non-repairable components can be bathtub shaped. Two change points can be defined for a bathtub failure rate curve, which can be viewed as the partition points between the early use, normal use and wear-out phases. There is practical significance to determine the change points, and several non-parametric methods have been developed for this purpose. This paper prese...

متن کاملComputation of Nonparametric Convex Hazard Estimators via Profile Methods Technical Report 542 Department of Statistics, University of Washington
Abstract. In this paper we develop an algorithm to find the maximum likelihood estimator of a convex hazard function. The maximization is done in two steps. First, we use the support reduction algorithm of [GJW1] to find the profile likelihood over a constrained space. We next show that (−1) times the profile likelihood is bathtub-shaped in the parameters, and use a bisection algorithm to find ...
متن کاملA new model with bathtub-shaped failure rate using an additive Burr XII distribution
It is a common situation that the failure rate function has a bathtub shape for many mechanical and electronic components. A simple model based on adding two Burr XII distributions is presented for modeling this type data. The graphical estimation on probability paper is illustrated, and examples of its usage are presented. The Akaike Information Criterion was used for judging the adequacy of t...
