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

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).
