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:

=
variable variance (one-dimensional)
multivariate mixture
"EII"
=

"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
