# mclustModelNames

##### MCLUST Model Names

Description of model names used in the *MCLUST* package.

- Keywords
- cluster

##### Usage

`mclustModelNames(model)`

##### Arguments

- model
A string specifying the model.

##### Details

The following models are available in package mclust:

univariate mixture |
||

`"E"` |
= | equal variance (one-dimensional) |

`"V"` |
= | variable variance (one-dimensional) |

multivariate mixture |
||

`"EII"` |
= | spherical, equal volume |

`"VII"` |
= | spherical, unequal volume |

`"EEI"` |
= | diagonal, equal volume and shape |

`"VEI"` |
= | diagonal, varying volume, equal shape |

`"EVI"` |
= | diagonal, equal volume, varying shape |

`"VVI"` |
= | diagonal, varying volume and shape |

`"EEE"` |
= | ellipsoidal, equal volume, shape, and orientation |

`"EVE"` |
= | ellipsoidal, equal volume and orientation (*) |

`"VEE"` |
= | ellipsoidal, equal shape and orientation (*) |

`"VVE"` |
= | ellipsoidal, equal orientation (*) |

`"EEV"` |
= | ellipsoidal, equal volume and equal shape |

`"VEV"` |
= | ellipsoidal, equal shape |

`"EVV"` |
= | ellipsoidal, equal volume (*) |

`"VVV"` |
= | ellipsoidal, varying volume, shape, and orientation |

single component |
||

`"X"` |
= | univariate normal |

`"XII"` |
= | spherical multivariate normal |

`"XXI"` |
= | diagonal multivariate normal |

(*) new models in mclust version >= 5.0.0.

##### Value
