gambaryan | R Documentation |
The function calculates a dissimilarity matrix based on the GA similarity measure.
gambaryan(data)
data |
A data.frame or a matrix with cases in rows and variables in columns. |
The Gambaryan similarity measure was presented in (Gambaryan, 1964). The measure assigns low weight to matches where the matching value occurs in about half the dataset, i.e., in between being frequent and rare, see (Borian et al., 2008).
The function returns an object of the class "dist".
