Clustering of variables in r
WebVariable clustering is used for assessing collinearity, redundancy, and for separating variables into clusters that can be scored as a single variable, thus resulting in data reduction. For computing any of the three similarity measures, pairwise deletion of NAs is done. The clustering is done by hclust (). http://math.furman.edu/~dcs/courses/math47/R/library/Hmisc/html/varclus.html

WebWith quantitative variables, distance calculations are highly influenced by variable units and magnitude. For example, clustering variable height (in feet) with salary (in rupees) having different units and distribution (skewed) will invariably return biased results. Hence, always make sure to standardize (mean = 0, sd = 1) the variables.
