Description: Functionality for reliability estimates. For
        'unidimensional' tests: Coefficient alpha, 'Guttman's'
        lambda-2/-4/-6, the Greatest lower bound and coefficient
        omega_u ('unidimensional') in a Bayesian and a frequentist
        version. For multidimensional tests: omega_t (total) and
        omega_h (hierarchical). The results include confidence and
        credible intervals, the probability of a coefficient being
        larger than a cutoff, and a check for the factor models,
        necessary for the omega coefficients. The method for the
        Bayesian 'unidimensional' estimates, except for omega_u, is
        sampling from the posterior inverse 'Wishart' for the
        covariance matrix based measures (see 'Murphy', 2007,
        <https://groups.seas.harvard.edu/courses/cs281/papers/murphy-2007.pdf>).
        The Bayesian omegas (u, t, and h) are obtained by 'Gibbs'
        sampling from the conditional posterior distributions of (1)
        the single factor model, (2) the second-order factor model, (3)
        the bi-factor model, (4) the correlated factor model ('Lee',
        2007, <doi:10.1002/9780470024737>).
