`model` |
A string specifying the model. |

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 |

`"XXX"` | = | ellipsoidal multivariate normal |

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

Returns a list with the following components:

`model` |
a character string indicating the model (as in input). |

`type` |
the description of the indicated model (see Details section). |
