## MCLUST Model Names

### Description

Description of model names used in the MCLUST package.

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

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

### Value

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).
