%description
Provides comprehensive tools for Bayesian model diagnostics and
comparison. Includes prior sensitivity analysis, posterior predictive
checks (Gelman et al. (2013) <doi:10.1201/b16018>), advanced model
comparison using Pareto-smoothed importance sampling leave-one-out
cross-validation (Vehtari et al. (2017) <doi:10.1007/s11222-016-9696-4>),
convergence diagnostics, and prior elicitation tools. Integrates with
'brms' (Burkner (2017) <doi:10.18637/jss.v080.i01>), 'rstan', and
'rstanarm' packages for comprehensive Bayesian workflow diagnostics.
