# MCMC sampling for dummies

When I give talks about probabilistic programming and Bayesian statistics, I usually gloss over the details of how inference is actually performed, treating it as a black box essentially. The beauty of probabilistic programming is that you actually don't have to understand how the inference works in order to build …

# The best of both worlds: Hierarchical Linear Regression in PyMC3¶

Today's blog post is co-written by my student Danne Elbers who is doing her masters thesis with me on computational psychiatry using Bayesian methods. This post also borrows heavily from a Notebook by Chris Fonnesbeck.

The power of Bayesian modelling …

# Hammer time: Nailing the emcee ensemble sampler onto PyMC

tl;dr: I hacked the emcee--The MCMC-Hammer ensemble sampler to work on PyMC models.

## Motivation¶

PyMC is an awesome Python module to perform Bayesian inference. It allows for flexible model creation and has basic MCMC samplers like Metropolis-Hastings. The upcoming PyMC3 will feature much fancier samplers like Hamiltonian-Monte Carlo …
