%description
Fits common univariate distributions using registered objective Bayesian
priors, including Jeffreys, reference, and maximal data information
priors, and supports user-defined distributions and priors through an
extensible model specification. Model-specific posterior propriety and
moment conditions are checked before computation when registered or
supplied. Exact simulation, marginalization, slice sampling, adaptive
Metropolis, and user-supplied posterior samplers share a common interface
for summaries, diagnostics, prediction, and pointwise log-likelihood
evaluation. A separate interface fits independently right-censored
observations using the registered complete-data priors, observed-data
likelihood sampling or data augmentation, with sufficient
posterior-propriety checks. Optional post-processing provides WAIC,
PSIS-LOO, and DIC for observed-data likelihoods. The reference-prior
framework follows Bernardo (1979)
