How to install and use HDDM

HDDM is a python package for drift diffusion model (DDM, see http://ski.clps.brown.edu/hddm_docs/). I used it to decompose the reaction time and accuracy data in my recent manuscript: Good Me Bad Me: Does Valence Influence Self-Prioritization During Perceptual Decision-Making. Here are a few tips on how to install and use HDDM, in case that you plan to replicate my analyses using the code and data I share here on Github.
