Exponential dispersion models and credibility

Scandinavian Actuarial Journal, 1998
Abstract The Exponential Dispersion Family is a rich family of distributions, comprised of several distributions, some of which are heavy-tailed and as such could be of significant relevance to actuarial science. The family draws its richness from a dispersion parameter σ 2 = 1/λ which is equal to 1 in the case of the Natural Exponential Family.

Exponential Dispersion Models and Extensions: A Review

International Statistical Review / Revue Internationale de Statistique, 1992
Summary: The paper reviews recent developments in the theory of exponential dispersion models and their various generalizations.Topics covered include dispersion models, exponential and proper dispersion models, stochastic processes, Tweedie's class of power variance functions [see \textit{M. C. K. Tweedie}, Proc. Camb. Philos. Soc.

Modeling exponential signals in a dispersive multipath environment

[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992
A technique for estimating parameters in exponential signals observed in a multipath environment, where multiple dispersive channels couple transmitter and receiver is presented. This multipath model simulates unique frequency dependent coefficients of attenuation and reflection along the different propagation paths, which can result in received ...

On Parameter Estimation for Exponential Dispersion Arma Models

Journal of Time Series Analysis, 2005
Abstract.  A class of autoregressive moving‐average (ARMA) models proposed by Jørgensen and Song [Journal of Applied Probability (1998), vol. 35, pp. 78–92] with exponential dispersion model margins are useful to deal with non‐normal stationary time series with high‐order autocorrelation.

A doubly restricted exponential dispersion model

Communications in Statistics - Theory and Methods, 2018
AbstractIn this paper, we propose and develop a doubly restricted exponential dispersion model, i.e. a varying dispersion generalized linear model with two sets of restrictions, a set of linear restrictions for the mean response, and at the same time, for another set of linear restrictions for the dispersion of the distribution.
