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.

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...

Generalized Weibull Linear Models

Communications in Statistics - Theory and Methods, 2010
For the first time, a new class of generalized Weibull linear models is introduced to be competitive to the well-known generalized (gamma and inverse Gaussian) linear models which are adequate for the analysis of positive continuous data. The proposed models have a constant coefficient of variation for all observations similar to the gamma models and ...

Weibull and inverse Weibull mixture models allowing negative weights

Reliability Engineering & System Safety, 1999
Abstract This article presents the finding that when components of a system follow the Weibull or inverse Weibull distribution with a common shape parameter, then the system can be represented by a Weibull or inverse Weibull mixture model allowing negative weights.

Bayesian predictions for compound weibull model

Communications in Statistics - Theory and Methods, 1980
This paper is concerned with a full Bayesian analysis for some prediction problems of the compound model if the underlying distributions are Weibull with unequal shape parameters and the sample is type I censored. A numerical example and computer facilities will be used to illustrate the procedure.

Weibull model selection for reliability modelling

Reliability Engineering & System Safety, 2004
A large number of models have been derived from the two-parameter Weibull distribution and are referred to as Weibull models. They exhibit a wide range of shapes for the density and hazard functions, which makes them suitable for modelling complex failure data sets.
