## Simulated Example Datasets From Baudry et al. (2010)

### 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 on 2 real variables.

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

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

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

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

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

### Examples

    ## Not run:
    data(Baudry_etal_2010_JCGS_examples)

    output <- clustCombi(data = ex4.4.1)
    output # is of class clustCombi

    # plots the hierarchy of combined solutions, then some "entropy plots" which
    # may help one to select the number of classes
    plot(output)

    ## End(Not run)
