Does it handle complex models like survival or zero-inflated analysis?

Absolutely, it includes templates for ordinal regression, zero-inflated/hurdle models, and parametric or semi-parametric survival models like Cox and Weibull.

Can this skill help with custom prior specification?

Yes, it provides implementation patterns for setting custom priors across different parameter classes and performing prior predictive checks to ensure your priors are reasonable.

What R packages does this skill support?

It primarily supports brms and rstanarm for modeling, bayesplot for visualization, loo for model comparison, and tidybayes for data manipulation.

Can I compare different Bayesian models using this skill?

Yes, it covers advanced model comparison techniques including LOO-CV, WAIC, and Bayes Factors, as well as model stacking for weighted predictions.

How does it assist with model validation?

The skill includes standard workflows for MCMC diagnostics (Rhat, ESS, trace plots) and posterior predictive checks (density overlays, interval plots) to ensure model convergence and fit.
