Bayesrel: Bayesian Reliability Estimation

Functionality for reliability estimates. For unidimensional tests: Coefficient alpha, 'Guttman's' lambda-2/-4/-6, the Greatest lower bound and coefficient omega in a Bayesian and a frequentist version. For multidimensional tests: omega-total and omega-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, 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 (unidimensional, hierarchical, and total) are obtained by 'Gibbs' Sampling from the conditional posterior distributions of (1) the single factor model and (2) the higher order factor model ('Lee', 2007, <doi:10.1002/9780470024737>).
