Package: BayesAiken Type: Package Title: Bayesian Content Validity Coefficients with Credibility Intervals Version: 2.0.0 Date: 2026-09-24 Authors@R: person("Jose", "Ventura-Leon", email = "jventuraleon@gmail.com", role = c("aut", "cre"), comment = c(ORCID = "0000-0003-2996-4244")) Description: Bayesian inference for the six rating coefficients proposed by Aiken (1985) and Aiken (1989) : 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.
