Bayesian Methods for Hackers: Probabilistic Programming and Bayesian Inference

2. A Little More on PyMC

2.1 Introduction

This chapter introduces more PyMC syntax and design patterns, and ways to think about how to model a system from a Bayesian perspective. It also contains tips and data visualization techniques for assessing goodness of fit for your Bayesian model.

2.1.1 Parent and Child Relationships

To assist with describing Bayesian relationships and to be consistent with PyMC’s documentation, we introduce parent and child variables.

Parent variables are variables that influence another variable.

Child variables
