What is the effect of country-specific characteristics on the research performance of scientific institutions? Using multi-level statistical models to rank and map universities and research-focused institutions worldwide
Lutz Bornmann, Moritz Stefaner, Felix de Moya Anegn, and Rdiger Mutz have introduced the tool www.excellencemapping.net. The tool visualizes the scientific performance of institutions within fields (e.g. chemistry) as ranking lists and on maps. Scopus data are used which have been collected for the SCImago Institutions Ranking. The enhanced version of the tool and the multilevel logistic regression on which it is based are described in this paper. The effect of covariates (such as the per capita GDP) on two performance metrics is examined and visualized.
