PUGMM Model Names

Description of the model names used in the PUGMM package.

pugmm_available_models()

The PUGMM model names in the PUGMM package are characterized by four letters:

First letter: it refers to the variable-group membership matrix V, which can be equal (E) or free to vary (F) across components.
Second, third, fourth letters: they refer to the matrices of the group variances \Sigma_{V}, the within-group covariances \Sigma_{W} and the between-group covariances \Sigma_{B}, respectively, by indicating if they are unique (U, i.e., equal within and across components), isotropic (I, i.e., equal within components), equal (E, i.e., equal across components) or free to vary across components (F).
