# BIC of estimated marginal gaussian mixture densities

### Description

Estimates the density of each covariates with gaussian mixture models and then gives the associated BIC.

### Usage

1 2 3 |

### Arguments

`X` |
the dataset (matrix) |

`nbclustmax` |
max number of clusters in the gaussian mixtures |

`nbclustmin` |
min number of clusters in the gaussian mixtures |

`verbose` |
verbose or not |

`detailed` |
boolean to give the details of the mixtures found |

`max` |
boolean. Use an heuristic to shrink nbclustmax according to the number of individuals in the dataset |

`package` |
package to use (Rmixmod,mclust) |

`nbini` |
number of initial points for Rmixmod |

`matshape` |
boolean to give the detail in matricial shape |

`...` |
additional parameters |

### Value

a list that contains:

`BIC_vect` |
vector of the BIC (one per variable) |

`BIC` |
global value of the BIC ( |

`nbclust` |
vector of the numbers of components |

`details` |
list of matrices that describe each Gaussian Mixture (proportions, means and variances) |

### Examples

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | ```
