%description
Provides methods for fitting the Mixture of Factor Analyzers (MFA) model
automatically. The MFA model is a mixture model where each sub-population
is assumed to follow the Factor Analysis model. The Factor Analysis (FA)
model is a latent variable model which assumes that observations are
normally distributed, but imposes constraints on their covariance matrix.
The MFA model contains two hyperparameters; g (the number of components in
the mixture) and q (the number of factors in each component Factor
Analysis model). Usually, the Expectation-Maximisation algorithm would be
used to fit the MFA model, but this requires g and q to be known. This
package treats g and q as unknowns and provides several methods which
infer these values with as little input from the user as possible.
