Hazard rate function in dynamic environment
Reliability Engineering & System Safety, 2014Abstract The hazard rate function is always applied to make maintenance policy, and the usual hazard rate function is computed by the data of failure times of systems working in constant environment, thus for systems working in dynamic environment it cannot be directly applied.

AbstractHazard rate processes are discussed in the context of doubly stochastic Poisson processes. We derive an explicit expression for the reliability function corresponding to an increasing hazard rate processes with independent increments. Also, bounds are obtained for the reliability function of a system with a general hazard rate process.

Beta Hazard Rate Distribution and Applications
IEEE Transactions on Reliability, 2015We introduce a new finite range life distribution with a hazard rate function of the form of a nonstandard beta density function. The hazard rate function is either increasing, or has a bathtub shape with a long flat middle interval. The proposed model has a simple structure.

For right-censored lifetime data with possible left-truncation, (1.6) of Example 1.3 defines penalized likelihood hazard estimation. Of interest are the selection of smoothing parameters, the computation of the estimates, and the asymptotic behavior of the estimates.

A comment on the beta hazard rate distribution
IEEE Transactions on Reliability, 2016We point out that the beta hazard rate distribution introduced by Lai and Jones is a particular case of Libby and Novick's beta distribution known since 1982.

The first chapter of this book recalled for the reader that Gnedenko, Belyaev and Solovyev [1] approved the bathtub curve after generic considerations. Now we can go back to this endorsement which constitutes a weak point of Gbedenko’s seminal work.

Inference for a hazard rate change point
Biometrika, 1991Summary: We discuss inference based on the likelihood ratio process for a hazard rate change point. A random change of time scale transforms the empirical process into a Poisson process which enables us to derive large deviation approximations to the significance level of the likelihood ratio test.

The analysis of unemployment duration in this study is based on the concept of the hazard rate and of the survivor function which were introduced in chapter II.2 about search theory. In the present chapter the design of explanatory hazard rate models for individual unemployment duration is considered in detail and empirical findings are surveyed.

A General Model for the Hazard Rate with Covariables
Biometrics, 1979with the coeffiicients of the various powers of time being possibly diffierent functions of the vector of covariables. Methods for fitting the model to data and testing hypotheses about model parameters are presented. The degree of the polynomial for the hazard is chosen in a step-wise manner as part of thefitting of the model.
