Classificando regimes políticos utilizando análise de conglomerados

the principal aim of this paper is to provide a intuitive introduction to cluster analysis. methodologically, we use data from coppedge, alvarez e maldonado (2008) regarding the two dimensions of polyarchy proposed by dahl (1971): contestation and inclusiveness. based on these dimensions we classify political regimes in different groups (clusters) according to their similarity level. on substantive grounds, we hope to suggest a methodological tool to classify political regimes and facilitate the understanding of cluster analysis in political science.
