A function for calculation of a proximity (dissimilarity) matrix based on the VM similarity measure.
A data.frame or a matrix with cases in rows and variables in colums.
The Variable Mutability similarity measure was introduced in (Sulc and Rezankova, 2019). It treats the similarity between two categories based on the within-cluster variability expressed by the normalized mutability. The measure assigns higher weights to rarer categories.
The function returns an object of class "dist".
