Description

Plot dotchart with the "loadings" of the variables in each cluster. The loading of a numerical variable is the correlation between this variables and the synthetic variable of its cluster. The loading of the level of a categorical variable is the mean value of the synthetic variable of the cluster on observations having this level.
