This page contains descriptions and links to:
a variational Bayesian toolbox for model-based analysis of neurobiological and behavioural data
a toolbox for group-level (random-effect) Bayesian model selection
a toolbox for the classification/clustering of multivariate data (Gibbs sampling and variational Bayesian algorithms)
a virtual Rubik's cube (for procrastinating adults only)
Here is my personal version of the VBA toolbox.
And here is a temporary version of the online MCD code.
