Document Details : Title: The Sample Size Needed for the Calculation of a GLM Tariff Author(s): SCHMITTER, H. Journal: ASTIN Bulletin Volume: 34 Issue: 1 Date: May 2004 Pages: 249-262 DOI: 10.2143/AST.34.1.504964 Abstract : A simple upper bound for the variance of the frequency estimates in a multivariate tariff using class criteria is deduced. This upper bound is based exclusively on univariate statistics and can, therefore, be calculated before a GLM analysis is carried out. It can be used to estimate the number of claims that will be needed for a tariff calculation depending on the number of tariff criteria and the number of levels of each criterion. The article is a revised version of a paper presented at the XXXIst ASTIN Colloquium in Porto Cervo. |
