Modeling with Weibull-Pareto Models

North American Actuarial Journal, 2012
Abstract In this paper we develop several composite Weibull-Pareto models and suggest their use to model loss payments and other forms of actuarial data. These models all comprise a Weibull distribution up to a threshold point, and some form of Pareto distribution thereafter.

Bayesian estimation for compound weibull model

Series Statistics, 1979
This paper is concerned with the Bayesian estimation problem of the unknown parameters of the compound Weibull model with unequal shape parameter. Bayesian estimates are obtained for the uniform and gamma prior probability densities assumming independent prior distributions.

A Weibull Model for the Estimation of Tumorigenic Potency

Biometrics, 1993
In this paper, a new method of estimating tumorigenic potency is proposed that takes into account information on survival and, when available, the underlying cause of death. Specifically, Weibull distributions are used to describe the time to tumor occurrence (X), the time to death as a result of tumor occurrence (Y), and the time of death from causes ...

Weibull Models

2003
A comprehensive perspective on Weibull models The literature on Weibull models is vast, disjointed, andscattered across many different journals. Weibull Models is acomprehensive guide that integrates all the different facets ofWeibull models in a single volume.

The McDonald Weibull model

Statistics, 2012
For the first time, we propose a five-parameter lifetime model called the McDonald Weibull distribution to extend the Weibull, exponentiated Weibull, beta Weibull and Kumaraswamy Weibull distributi...

2-acetylaminofluorene and the Weibull model

Food and Cosmetics Toxicology, 1981
Abstract The Weibull model for dose-response functions in carcinogenesis is explored with respect to the results from the large experiment with 2-acetylaminofluorene (2-AAF). Several generalized forms of the Weibull model are presented. Also, the hypothesis of ‘low-dose linearity’ is tested with the data for 2-AAF.

A Bivariate Weibull Regression Model

Economic Quality Control, 2005
Summary: We propose a new bivariate Weibull regression model based on censored samples with common covariates. There are some interesting biometrical situations which motivate the study of a bivariate Weibull regression model of the proposed type. A procedure for obtaining the maximum likelihood estimators for the parameters in the model is derived and

WEIBULL MODELING OF THE FENTON'S OXIDATION PROCESS

Journal of Environmental Science and Health, Part A, 2001
A modified version of the two-parameter Weibull survival curve is used to investigate its applicability to analyze the influence of the Fenton's Reagent on the decomposition of 2,4-dinitrophenol solutions (DNP). Fenton's Reagent is one type of advanced oxidation processes (AOPs) in which strong oxidants, hydroxyl radicals, are generated.

Weibull multi-state models with misclassification

Communications in Statistics - Simulation and Computation, 2017
It is often important to allow multi-state models (MSMs) to accommodate misclassification of states.
