Description: This paper develops a parametric model for health care insurance claims to fit parametric models to the data. Model selection is based on the ChJ-squared goodness-of-fit test and a comparison of the empirical limited expected value function to parametric limited expected value functions. A copula function was used to model the bivariate portion of the data. From Actuarial Research Clearing House 1993, VOL. 3.

An alternative was presented. From Actuarial Research Clearing House 1993, VOL. 3.

Description: This Fellowship credit research paper describes the use of fuzzy sets applications to the selection of group health risks.
