Code, tools, talks

I routinely place research code and data in the public domain. These are spread across GitHub and the Open Science Framework. Code relating to specific papers can be found on the publications page. I’ve also placed research talks and other resources below.

Bayesian Cognitive Modelling

Bayesian analysis of delay discounting data

I produced a package, currently implemented in Matlab, which conducts hierarchical Bayesian inference on delay discounting data. This package allows you to generate posterior distributions of discounting parameters. 

Vincent, B. T. (2016). Hierarchical Bayesian estimation and hypothesis testing for delay discounting tasks. Behavior Research Methods. 48(4), 1608-1620. [project page | pdf | code]

Since then, I have moved on to conduct Bayesian scoring of delay discounting data in Python for a number of other papers, for example here, here, and here.

Delay discounting: interactive web apps

I have built a number of handy tools to interactively explore how discounting works. These are built using R and Shiny and the code is available here.

Bayesian statistics

Below is a list of notes and resources that I am slowly accumulating on Bayesian statistical methods.
