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
作者：
Highlights：
• Lutz Bornmann, Moritz Stefaner, Felix de Moya Anegón, and Rüdiger 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.
