MdsDimChoice: Computation of the stress of Mds solution

Description

MdsDimChoice() returns a table of stress values of Multidimensionnal scaling for different dimensions. The different dimensions to test are given as an argument of the function.

The Mds is based on smacof algorithm and may be metric or not metric.

Usage

MdsDimChoice(Part, dimen = c(2, 4), metric = FALSE,
        ties = "primary", itmax = 5000, eps = 1e-06)

Arguments

Part

Part is an object of class SortingPartition

dimen

Vector of (minimum and maximum of) dimensions for Mds (default is dimen=c(2,4))

metric

Metric or non metric Mds (default is metric=FALSE for non metric Mds)

ties

Treatment of ties in case of non metric Mds

itmax

Maximum number of iterations

eps

Epsilon for Mds computation

Value

Table of Kruskal stress for the chosen dimensions

Examples

# NOT RUN {
  data(AromaSort)
  Aroma<-SortingPartition(AromaSort)
  tabres<-MdsDimChoice(Aroma)
# }
