This tutorial introduces the computational cluster at the Duke Brain Imaging and Analysis Center (BIAC) and presents a few simple use cases. Hopefully it will make your experience handling/analyzing neural...

Ordinal regression models to analyze Likert scale data

Today I am going to present on an alternative way to analyze Likert scale data by using ordinal regression instead of linear regression. But first, why is it even a...

Fitting drift-diffusion models with simulation

Last week, Raphael presented a fantastic conceptual introduction to drift diffusion models, which are an extension of signal detection models over time. Here I’ll be talking about what model fitting...
