vm {nomclust} | R Documentation |
A function for calculation of a proximity (dissimilarity) matrix based on the VM similarity measure.
vm(data)
data |
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".
