In villardon/MultBiplotR: Multivariate Analysis Using Biplots in R

Description

Gower Dissimilarities for mixed types of data

Usage

  GowerSimilarities(x, y = NULL, Classes = NULL, transformation =
                   "sqrt(1-S)", BinCoef = "Simple_Matching", ContCoef =
                   "Gower", NomCoef = "GOW", OrdCoef = "GOW")

Arguments

x	Main data. Distances among rows are calculated if y=NULL. Must be a data frame.
y	Suplementary data matrix. If not NULL the distances among the rows of x and y are calculated. Must be a data frame with the same columns as x.
Classes	Vector containing the classes of each variable.
transformation	Transformation to apply to the similarities.
BinCoef	Coefficient for the binary data
ContCoef	Coefficient for the continuous data
NomCoef	Coefficient for the nominal data
OrdCoef	Coefficient for the ordinal data

Details

Gower Dissimilarities for mixed types of data. The transformation sqrt(1-S) is applied to the similarity by default.

Value

An object of class proximities.This has components:
