Mixture Models with Component-Wise Factor Analyzers
Description
We provide functions to fit finite mixtures of multivariate normal or t-distributions to
data with various factor analytic structures adopted for the covariance/scale matrices. The
factor analytic structures available include mixtures of factor analyzers and mixtures of common
factor analyzers. The latter approach is so termed because the matrix of factor loadings is
common to components before the component-specific rotation of the component factors to
make them white noise. Note that the component-factor loadings are not common after
this rotation. Maximum likelihood estimators of model parameters are obtained via the
Expectation-Maximization algorithm. See descriptions of the algorithms used in
