Description: This paper expands the calculation of a group's credibility factor from a traditional univariate one-dimensional single layer model to: 1. a univariate one dimensional two layer model, 2. a multivariate one dimensional single layer model, and 3. a univariate two dimensional single layer models.

Description: This paper introduces the alternative notion of 'corresponding conditional single-decrement models.' These models: 1. do have both an intuitive and a precise probabilistic meaning, 2. do behave as do standard single-decrement models, 3. can easily be used to construct the full multiple-decrement model without any special assumption.

Description: This is correction to a paper entitled 'Six Bridges to psi,' which was printed in ARCH 1993 Vol 1. From ACTUARIAL RESEARCH CLEARING HOUSE 1994, VOL. 1.

Description: Describes purpose of ARCH and editorial policy.

Description: Because actuaries fit models for a variety of situations, particularly with regard to data modifications, it is useful to have a single approach. Though not optimal or exact for a particular model or data structure, the method should be reasonable for most all settings. Such a method is proposed in this article.

Description: Discusses a method for division of workload in a consulting firm in a way which will minimize cost.

Description: Two renewal processes, known in reliability maintenance as minimal repair and replacement policy, are introduced in this paper. Their properties are studied in the case where the generating random sequence has a distribution with periodic failure rate. Applications in risk theory are shown. From Actuarial Research Clearing House 1993, VOL. 1.

Description: This paper considers several features in a model that experiences gradual drifts and jumps for prevalence and survivorship as is the case for AIDS. It is an actuarial model for AIDS when transition intensities follow jump-diffusion processes.

Description: This is a presentation on computing tight bounds for insurance payments with nonlinear risk. Semi-definite Programming is defined, some examples are presented, and non-linear applications are presented. From Actuarial Research Clearing House, 2012, Vol.1.

Description: This paper shows that credibilty theory and Parametric Empirical Bayes [PEB] theory are closely related and applies PEB theory to credibility applications for normal and other familiar probability distributions.
