Description: Bayesian inference for the six rating coefficients proposed by
    Aiken (1985) <doi:10.1177/0013164485451012> and Aiken (1989)
    <doi:10.1177/0013164489492003>: V (content validity), H (homogeneity),
    C (congruence), R (repeatability), A (rater agreement) and I (item
    coherence). All six are expressed as functionals of the population
    distribution of rating categories, so a single Dirichlet-Multinomial model
    yields their full posterior by push-forward. This treats each judge as one
    categorical observation and avoids the pseudo-replication of Beta-Binomial
    formulations. R is modelled on the c-by-c joint table because it is not a
    functional of the marginal distribution. Provides classical estimates with
    the correct parity correction, highest density and equal-tailed
    credibility intervals, posterior threshold probabilities, prior
    sensitivity analysis and a friendly step-by-step verbose report.
