Does it handle non-centered parameterization?

Absolutely. It provides specific code patterns for non-centered parameterization to help resolve divergent transitions often found in hierarchical models.

Can this skill help with MCMC diagnostics?

Yes, it includes specific guidance on monitoring Rhat, Effective Sample Size (ESS), divergences, and performing posterior predictive checks.

What version of Stan does this skill support?

It is optimized for Stan 2.37 and newer, utilizing modern syntax such as the 'array' keyword and updated distribution parameterizations.

Is this skill compatible with R integration?

Yes, it includes templates for cmdstanr, allowing you to sample, diagnose, and compare models (LOO/WAIC) directly within an R environment.

Provides foundational knowledge and best practices for developing, optimizing, and reviewing Stan 2.37 probabilistic models.

This skill equips Claude with the specific syntax, structural requirements, and statistical best practices needed to build robust Bayesian models in Stan. It covers the essential seven-block program structure, the modern array syntax, constrained variable types, and efficient vectorization techniques. Whether you are translating models from BUGS/JAGS or building new hierarchical models from scratch, this skill ensures the resulting code follows modern Stan conventions (version 2.37+) and integrates seamlessly with R-based workflows like cmdstanr and the bayesplot ecosystem for comprehensive model diagnostics.
