Baudry_etal_2010_JCGS_examples: Simulated Example Datasets From Baudry et al. (2010)

In RmixmodCombi: Combining Mixture Components for Clustering

Description

Simulated Datasets used in Baudry et al. (2010) to illustrate the proposed mixture components combining method for clustering.

Please see the cited article for a detailed presentation of these datasets. The data frame with name exN.M is presented in Section N.M in the paper.

Test1D (not in the article) has been simulated from a Gaussian mixture distribution in R.

ex4.1 and ex4.2 have been simulated from a Gaussian mixture distribution in R^2.

ex4.3 has been simulated from a mixture of a uniform distribution on a square and a spherical Gaussian distribution in R^2.

ex4.4.1 has been simulated from a Gaussian mixture model in R^2

ex4.4.2 has been simulated from a mixture of two uniform distributions in R^3.

Usage

data(Baudry_etal_2010_JCGS_examples)

Format

ex4.1 is a data frame with 600 observations of 2 real variables.

ex4.2 is a data frame with 600 observations of 2 real variables.

ex4.3 is a data frame with 200 observations of 2 real variables.

ex4.4.1 is a data frame with 800 observations of 2 real variables.

ex4.4.2 is a data frame with 300 observations of 3 real variables.

Test1D is a data frame with 200 observations of 1 real variable.

Examples

set.seed(1)

data(Baudry_etal_2010_JCGS_examples)

output <- mixmodCombi(ex4.4.2, nbCluster = 1:10, 
models = mixmodGaussianModel(listModels = "Gaussian_pk_Lk_Ck")) 

output # is of class MixmodCombi

## Not run: 
plot(output) # plots the hierarchy of combined solutions, then some "entropy plots" 
# which may help to select the number of classes

## End(Not run)
