heterog.parti

R Documentation

heterogeneity of a partition obtained with the method `hclust.geo.H`.

Description

This function calculate the heterogeneity of a partition as the sum of the heterogeneity of all classes obtained withheterog.Ck.

Usage

heterog.parti(dist.var, dist.geo, partition, wt, alpha)

Arguments

`dist.var`	a square symetric matrix with the distances between individuals measured on the variables.
`dist.geo`	a square symetric matrix with the geographical distances between individuals.
`partition`	a vector of size `n` giving the belonging of each individuals to each class of individuals.
`wt`	a vector of size `n` whose values indicate weights of individuals on quantitative variables
`alpha`	a real between 0 and 1 to fit the global criterion to optimize

Details

Note that in the calcul of Inertia, the two matrices of distances are normalized (divided by their own maximum).

Value

res a list containing the following results : the Inertia of the partition based on dist.var, the Inertia of the partition based on dist.geo, the heterogeneity of the partition as defined in description.
