Hi, Version 0.4 of 'catlearn' is now available for Windows, Mac, and Linux. This update adds three model implementations: * COVIS (Ashby et al., 1998) - lead programmer: Angus Inkster * DIVA (Kurtz, 2007) - lead programmer: Garrett Honke * Rescorla-Wagner (1972) - lead programmer: Stuart Spicer 'catlearn' is a free and open archive of model implementations, data sets, and simulations, designed to facilitate collaboration on the formal modeling of psychological processes, see: http://catlearn.r-forge.r-project.org/ If you are going to the ICPS conference in Vienna this month, you might like to attend the half-way workshop I'm running on catlearn: A Practical Introduction to Distributed Collaboration for Formal Modeling ICPS, Vienna Thu, Mar 23, 10:30am - 1:20pm, Hall N2. You can also join the mailing list at: https://lists.r-forge.r-project.org/mailman/listinfo/catlearn-package 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. * 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
