PyMC Bayesian Modeling

Skill Verifiziert Aktiv

Bayesian modeling with PyMC. Build hierarchical models, MCMC (NUTS), variational inference, LOO/WAIC comparison, posterior checks, for probabilistic programming and inference.

Zweck

To enable AI agents to perform advanced Bayesian statistical modeling and probabilistic programming tasks using PyMC.

Funktionen

  • Build and fit Bayesian models with PyMC
  • Implement hierarchical models and non-centered parameterization
  • Perform MCMC sampling (NUTS) and variational inference (ADVI)
  • Conduct prior and posterior predictive checks
  • Compare models using LOO and WAIC
  • Analyze sampling diagnostics and troubleshoot issues

Anwendungsfälle

  • Building complex hierarchical models for grouped data
  • Performing uncertainty quantification through Bayesian inference
  • Validating model assumptions and fit using predictive checks
  • Comparing multiple statistical models to find the best fit
  • Implementing advanced statistical analyses in research workflows

Nicht-Ziele

  • Performing basic frequentist statistical tests
  • Building machine learning models not based on Bayesian principles
  • Automating data collection or external API calls beyond model parameterization

Workflow

  1. Prepare and standardize data
  2. Build the Bayesian model structure with PyMC
  3. Perform prior predictive checks
  4. Fit the model using MCMC or VI
  5. Check sampling diagnostics (R-hat, ESS, divergences)
  6. Validate model fit with posterior predictive checks
  7. Analyze model parameters and make predictions

Praktiken

  • Bayesian modeling workflow
  • Prior selection and validation
  • Model diagnostics and convergence checking
  • Hierarchical model construction
  • Model comparison and selection

Voraussetzungen

  • Python 3.11+
  • PyMC installed
  • ArviZ installed
