Example code for doing MIRT (multidimensional item response theory) simulations in Python using PyMC

About

This is some example code for doing MIRT (multidimensional item response theory) simulations in Python using PyMC.

Requirements

PyLab

PyMC

Usage

Run simulation.py, toggling the generating variable to switch between generating mode (where we assume we know the underlying learner proficiencies, and generate a set of responses) and non-generating mode (when all we know is the responses, and we want to infer the underlying proficiencies).
