Abstract
In this paper we present a method of calculating Bühlmann-Straub credibility factors using standard statistical techniques developed for the analysis of variance. Emphasis is placed on using readily available statistical packages such as SAS and SPSS. Additionally many other computational tools such as EXCEL can be programmed to make such calculations. An example and some sample SAS programs are provided.
Key words and phrases: Bühlmann-Straub credibility factors, empirical Bayes, borrowing strength, random ANOVA model.
