Document Details : Title: Improved Approximations for the Aggregate Claims Distribution in the Individual Model Author(s): HIPP, Christian Journal: ASTIN Bulletin Volume: 16 Issue: 2 Date: November 1986 Pages: 89-100 DOI: 10.2143/AST.16.2.2015001 Abstract : Kornya-type higher order approximations are derived for the aggregate claims distribution and for stop loss premiums in the individual model with arbitrary positive claims. Absolute error bounds and error bounds based on concentration functions are given. In the Gerber portfolio containing 31 policies, second order approximations lead to an accuracy of 3 × 10-4, and third order approximations to 1.7 × l0-5. |
