Laplace-Weibull Mixtures for Modeling Price Changes

Management Science, 1993
B. Mandelbrot and E. Fama in the sixties, and W. Ziemba in the seventies, suggested stable laws for modeling stock returns and commodity prices. Geometric stable distributions, with Laplace distribution playing the role of a “normal” law, have been found to give better fit to such data.

A diagnostic approach to Weibull‐Weibull stress‐strength model and its generalization

International Journal of Quality & Reliability Management, 2011
PurposeThe objective of the paper is to consider the problem of the strength of a manufactured item against stress, when the component follows Weibull failure law. Different cases of stress and strength with varying parameters are discussed for the Weibull‐Weibull stress‐strength model considered in this paper. The application of the proposed technique

Models involving two inverse Weibull distributions

Reliability Engineering & System Safety, 2001
In this paper, we look at three models (mixture, competing risk and multiplicative) involving two inverse Weibull distributions. We study the shapes of the density and failure-rate functions and discuss graphical methods to determine if a given data set can be modelled by one of these models. (C) 2001 Elsevier Science Ltd.

Weibull Mixture Model for Reliability Analysis

International Review of Electrical Engineering (IREE), 2014
In reliability analysis, electrical systems can have more than one failure mode .For example, systems may have been used in different operating environments or there could be differences in design and /or material. In these cases, failure time data of systems would not fall on a straight line on a Weibull probability paper.

Sensitivity in Weibull System Reliability Models

Annual Reliability and Maintainability Symposium, 1984. Proceedings., 2005
Sensitivity of a Weibull distribution based model of complex-system reliability is investigated analytically and numerically. The complex system modeled is a central processing unit product. The types of sensitivity examined are that of the reliability model to erroneous parameter estimates, to improvements or degradations in component performance, and

Kinetic modeling of native Cassava starch thermo‐oxidative degradation using Weibull and Weibull‐derived models

Biopolymers, 2013
ABSTRACTA new approach in kinetic modeling of thermo‐oxidative degradation process of starch granules extracted from the Cassava roots was developed. Based on the thermoanalytical measurements, three reaction stages were detected. Using Weibull and Weibull‐derived (inverse) models, it was found that the first two reaction stages could be described with
