We use Principal Component Analysis (PCA) perform a mapping our data lower-dimensional space, further analyse causal relationships principal using partial correlation coefficients, concluding two twelve main can be explained ten independent sub-pillars. Thereafter, we cluster analysis group objects (i.e. countries) into clusters.
