Description of model names used in the MCLUST package.
mclustModelNames(model)A string specifying the model.
Returns a list with the following components:
a character string indicating the model (as in input).
the description of the indicated model (see Details section).
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" |
