Characterization of tails through hazard rate and convolution closure properties

, 2011
We use the properties of the Matuszewska indices to show asymptotic inequalities for hazard rates. We discuss the relation between membership in the classes of dominatedly or extended rapidly varying tail distributions and corresponding hazard rate ...

Decision aid problems criteria for infrastructure networks vulnerability analysis (regular paper) [PDF]

, 2013
Natural disasters through infrastructure networks might aggravate or mitigate consequences to stakes. The objective of this paper is to characterize this kind of situation in order to provide a solid foundation for the decision aid. This characterization

NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES [PDF]

, 2010
The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity ...

Informing Selection of Nanomaterial Concentrations for ToxCast In Vitro Testing based on Occupational Exposure Potential [PDF]

, 2011
Background: Little justification is generally provided for selection of in vitro assay testing concentrations for engineered nanomaterials (ENMs). Selection of concentration levels for hazard evaluation based on real-world exposure scenarios is desirable.

Nonparametric estimation of a convex bathtub-shaped hazard function

, 2010
In this paper, we study the nonparametric maximum likelihood estimator (MLE) of a convex hazard function. We show that the MLE is consistent and converges at a local rate of $n^{2/5}$ at points $x_0$ where the true hazard function is positive and ...

Integrating asthma hazard characterization methods for consumer products

Regulatory Toxicology and Pharmacology, 2014
Despite extensive study, definitive conclusions regarding the relationship between asthma and consumer products remain elusive. Uncertainties reflect the multi-faceted nature of asthma (i.e., contributions of immunologic and non-immunologic mechanisms).

An adverse selection model of optimal unemployment insurance [PDF]

We derive the shape of optimal unemployment insurance (UI) contracts when agents can exert search effort but face different search costs and have private information about their type.

Characterizations of some bivariate models using reciprocal coordinate subtangents

Statistica, 2014
In the present paper, we consider the bivariate version of reciprocal coordinate subtangent (RCST) and study its usefulness in characterizing some important bivariate models.
