What problem does it solve?

PyMC Bayesian Modeling enables building rigorous probabilistic models, allowing practitioners to quantify uncertainty and make data-driven decisions with principled inference.

Core Features & Use Cases

  • Hierarchical/multilevel modeling with MCMC (NUTS) and variational inference
  • Model comparison via LOO/WAIC and posterior predictive checks
  • End-to-end workflow: data preparation, priors, fitting, diagnostics, and prediction
  • Extensive tutorials and templates for linear, logistic, and hierarchical models

Quick Start

Train a simple Bayesian linear model with PyMC, fit it to your data, and inspect the posterior results.

FAQPage Schema
How do I quantify uncertainty in predictive modeling using Bayesian methods?

You can quantify uncertainty in predictive modeling by applying Bayesian inference with PyMC, which supports priors selection, NUTS sampling, and posterior predictive checks to provide principled uncertainty estimates for your data-driven decisions.

How do I build and fit a hierarchical model with PyMC?

Build and fit a hierarchical model with PyMC by defining multilevel priors, drawing posterior samples using NUTS or variational inference, and validating results using posterior predictive checks and ArviZ diagnostics.

Can I compare Bayesian models using LOO and WAIC in Python?

Yes, you can compare Bayesian models using LOO and WAIC criteria to evaluate predictive accuracy, running model comparison alongside posterior predictive checks to select the best fitting architecture for your data.

Does this Bayesian workflow support both MCMC and variational inference?

Yes, the Bayesian workflow supports both MCMC NUTS sampling and variational inference, allowing you to fit linear, logistic, and hierarchical models and extract posterior distributions for forecasting and analytics.

What's the best way to run posterior predictive checks after MCMC sampling?

Run posterior predictive checks after MCMC sampling by generating replicated data from your fitted PyMC model and analyzing the distributions with ArviZ to validate that your model accurately captures the observed data patterns.

How do I prepare data and select priors for a Bayesian logistic model?

Prepare data using pandas and numpy arrays, then select appropriate priors for your Bayesian logistic model in PyMC, ensuring your probability distributions accurately reflect domain knowledge before initiating NUTS sampling.
