Builds and analyzes robust Bayesian statistical models using Stan-based R packages like brms and rstanarm.
This skill empowers Claude to perform high-level Bayesian statistical modeling within the R ecosystem, leveraging the power of Stan through user-friendly interfaces like brms and rstanarm. It provides a structured workflow for specifying complex models—including linear, logistic, mixed-effects, and non-linear architectures—defining custom priors, conducting posterior predictive checks, and performing rigorous model comparison using LOO and WAIC. It is an essential tool for data scientists and researchers who need to quantify uncertainty and incorporate domain knowledge into their statistical analyses while following modern Bayesian workflow best practices.
