PyMC Bayesian Modeling Overview PyMC is a Python library for Bayesian modeling and probabilistic programming. Build, fit, validate, and compare Bayesian models using PyMC's modern API (version 5.x+), including hierarchical models, MCMC sampling (NUTS), variational inference, and model comparison (LOO, WAIC). When to Use This Skill This skill should be used when: Building Bayesian models (linear/logistic regression, hierarchical models, time series, etc.) Performing MCMC sampling or variational inference Conducting prior/posterior predictive checks Diagnosing sampling issues (divergences, convergence, ESS) Comparing multiple models using information criteria (LOO, WAIC) Implementing uncertainty quantification through Bayesian methods Working with hierarchical/multilevel data structures Handling missing data or measurement error in a principled way Standard Bayesian Workflow Show more
