The Reversed Hazard Rate Function
Probability in the Engineering and Informational Sciences, 1998In this paper we discuss some properties of the reversed hazard rate function. This function has been shown to be useful in the analysis of data in the presence of left censored observations. It is also natural in discussing lifetimes with reversed time scale.

Generation of hazard identification functions
Fourth International Symposium on Quality Electronic Design, 2003. Proceedings., 2004We study the problem of identifying the complete set of pairs of input patterns that can cause different types of hazards to appear at a circuit line. A novel methodology to implicitly identify all possible input configurations is proposed. The technique is based on a systematic derivation of the conditions for the occurrence of static and dynamic ...

Bayesian Estimators for Conditional Hazard Functions
Biometrics, 2000Summary.This article introduces a new Bayesian approach to the analysis of rightâcensored survival data. The hazard rate of interest is modeled as a product of conditionally independent stochastic processes corresponding to (1) a baseline hazard function and (2) a regression function representing the temporal influence of the covariates.

Tutorial on Discrete Hazard Functions
Quality Management in Health Care, 2007Risk analysis requires estimation of hazard functions. A hazard rate is the conditional probability of adverse sentinel event occurring in the next time period, given that it has not yet occurred. This tutorial shows how hazard functions are estimated from survival functions, the probability of going through a time period without the sentinel event ...

Transportation Research Record: Journal of the Transportation Research Board, 2011
Hazard models are used only moderately in the transportation field compared with their levels of application in other areas, such as medicine, political science, and economics. Many specifications of the hazard models are not well known, whereas the primary application of hazard models is limited to a basic proportional continuous hazard formulation ...

Hazardous workspace modeling for manipulators using spatial hazard functions
2012 IEEE International Symposium on Safety, Security, and Rescue Robotics (SSRR), 2012This paper describes an approach to motion planning that includes hazards individually characterized as continuous functions of space. These functions contribute to a complex and discontinuous yet practical representation of the hazards found in a manipulator's workspace.

Hazard function estimators: a simulation study
Statistics in Medicine, 1999Kernel-based methods for the smooth, non-parametric estimation of the hazard function have received considerable attention in the statistical literature. Although the mathematical properties of the kernel-based hazard estimators have been carefully studied, their statistical properties have not.

Epidemiologia e prevenzione, 2008
In cohort studies the event occurrence is usually described by the incidence rate and the survivor function. In comparison with these estimators the plot of the hazard function has the advantage to show the variations of the occurrence of the event along the period of observation, which often are important to be highlighted. Furthermore, when comparing
