Procedures for linking international comparisons

Abstract

Problems of linking international comparisons became significant with the growing number of regional projects and the wish to compile intra- or intercontinental or even worldwide results from the regional exercises. The related tasks and methods of linking can be systematized with the help of some basic notions, like closed system, chain-linking, etc. Starting from simple cases (inclusion of an additional country in an existing comparison, linking two comparisons), more complicated procedures (linking several regions, etc.) can be explored.
