Hi, I've just released 'catlearn', a free and open archive designed to facilitate collaboration on the formal modeling of psychological processes, see: http://catlearn.r-forge.r-project.org/ You can also join the mailing list at: https://lists.r-forge.r-project.org/mailman/listinfo/catlearn-package Catlearn is intended to be a community-sourced archive of model implementations, and independently-replicated data sets against which to test them, and also an archive of those simulations. The project is discussed in detail in a forthcoming "Psychology of Learning and Motivation" article - a copy is available on request. I'm also happy to give a presentation or workshop if that would be of interest. Finally, I'm particularly keen to talk to you, and assist, if... * You have a formal model you'd like to make publicly available in this archive. I have already implemented ALCOVE with the archive, and we're working on COVIS. * You have ideas for independently-replicated phenomena that could be included in the archive. * You'd like to publicly archive your simulations of datasets with models. All the best Prof. Andy Wills School of Psychology Plymouth University, UK www.willslab.co.uk
