Testing for random effects in compound risk models via Bregman divergence

H Jeong - ASTIN Bulletin: The Journal of the IAA, 2020 - cambridge.org
The generalized linear model (GLM) is a statistical model which has been widely used in
actuarial practices, especially for insurance ratemaking. Due to the inherent longitudinality of …

In this paper, reference analysis, the tool provided by Berger et al.(2009), is used to obtain
reference Bayesian premiums, which can be helpful when the practitioner has insufficient …

Principal applications of Bayesian methods in actuarial science: a perspective

UE Makov - North American Actuarial Journal, 2001 - Taylor & Francis
Bayesian ideas were introduced into actuarial science in the late 1960s in the form of
empirical credibility methods for premium setting. The advance of the Bayesian methodology …

Measuring sensitivity in a bonus–malus system

E Gómez, A Hernández, JM Pérez… - Insurance: Mathematics …, 2002 - Elsevier
In performing Bayesian analysis of a bonus–malus system (BMS) it is normal to choose a
parametric structure, π0 (λ), in the insurer's portfolio. According to Bayesian sensitivity …

On the consistency of credibility premiums regarding Esscher principle

M Pan, R Wang, X Wu - Insurance: Mathematics and Economics, 2008 - Elsevier
In this paper, we investigate the problems of convergence of experience-based ratemakings
regarding the Esscher principle. In addition to the Bayes and the classical credibility …

Truncated stop loss as optimal reinsurance agreement in one-period models

M Kaluszka - ASTIN Bulletin: The Journal of the IAA, 2005 - cambridge.org
We consider several one-period reinsurance models and derive a rule which minimizes the
ruin probability of the cedent for a fixed reinsurance risk premium. The premium is calculated …

[PDF][PDF] Robust Bayesian prediction with asymmetric loss function in Poisson model of insurance risk

A Boratyńska - Acta Universitatis Lodziensis. Folia Oeconomica, 2006 - bibliotekanauki.pl
In robust Bayesian analysis a prior is assumed to belong to a family instead of being
specified exactly. The multiplicity of priors leads to a collection of Bayes actions. It is clearly …

Posterior regret Γ-minimax estimation of insurance premium in collective risk model
