Description: Implements three families of parsimonious hidden Markov
        models (HMMs) for matrix-variate longitudinal data using the
        Expectation-Conditional Maximization (ECM) algorithm. The
        package supports matrix-variate normal, t, and contaminated
        normal distributions as emission distributions. For each hidden
        state, parsimony is achieved through the eigen-decomposition of
        the covariance matrices associated with the emission
        distribution. This approach results in a comprehensive set of
        98 parsimonious HMMs for each type of emission distribution.
        Atypical matrix detection is also supported, utilizing the
        fitted (heavy-tailed) models.
