Seminar: Introduction to Bayesian Data Analysis & Cognitive Modeling
R tutorial
There will be an R tutorial on Thur June 14, 1 pm in the Cave. Please feel free to bring your laptops (it’s actually recommended). In preparation for the tutorial, please download and install R from here (or some other mirror):
and ALSO please …
read moreGaussian Mixtures
We introduced Gaussian mixtures today and discussed how to estimate their parameters with R & JAGS for finite mixtures and the R package “DPpackage” for infinite (Dirichlet Process) mixtures. As we mentioned in our concluding discussion today, there is a very wide range of possible linguistic applications for this kind of …

On April 26, Jakub Dotlacil presented recent and ongoing work with Adrian Brasoveanu on the semantics and processing of distributivity, reporting the results of 3 eye-tracking experiments that investigated:
- whether distributive vs. collective readings for plural definites are a matter of ambiguity or vagueness (building on previous work by Frazier …
Improved ANOVA scripts in Kruschke’s DBDA
John Kruschke made a couple of changes to the hierarchical Bayesian ANOVA scripts in his “Doing Bayesian Data Analysis” book. An important one is changing the hyperprior on the SD parameter. Here’s a lightly edited quote:

SIMPLE and SDT
The R & JAGS scripts we used today to discuss ch. 12 “The SIMPLE Model of Memory” and ch. 11 “Signal Detection Theory” of Lee & Wagenmakers (“Bayesian Cognitive Modeling: A Practical Course”, to appear) are available here: ch-12-LW.r and ch-11-LW.r. As we mentioned during the meeting, these …

The R & JAGS script we used today to discuss ch. 10 “Individual Differences in Memory Retention” of Lee & Wagenmakers (“Bayesian Cognitive Modeling: A Practical Course”, to appear) is available here: ch-10-LW.r. As we mentioned during the meeting, this chapter is an intro to random-effects models (random effects by …
