(apologies for cross-posting) I would like to announce the release of CAST 4.1. Changes from release 4.0 are a new agricultural experiments e-book and improvements to the industrial experiments e-book. CAST is a free resource for teaching statistics that makes extensive use of dynamic diagrams (applets) to teach statistical concepts. It has a practical focus and contains: Three introductory statistics e-books for self-study with about 450 applets each (biometrics, business and general). Three advanced e-books about multiple regression & GLMs (265 applets), experimental design for agriculture & biology (168 applets) and industrial experiments (95 applets). A set of about 100 introductory exercises whose questions have random aspects and that give feedback about mistakes. (The exercises have various formats -- not just multiple choice.) The introductory applets are also provided as a separate collection of larger diagrams for use in lectures -- most lecture courses would benefit from use of some of these applets. CAST is freely available under a Creative Commons licence. It can be used directly from: http://cast.massey.ac.nz However to reduce load on our server, we would prefer it to be downloaded onto a local hard disk or server and run from there. (Click the Download tab in the main CAST page for information.) _____________________________________________________________ Doug Stirling Email: [log in to unmask] Institute of Fundamental Sciences Massey University Ph: (64)-6-350-5799, ext 2481 Palmerston North 4442 Fax: (64)-6-350-5682 New Zealand _____________________________________________________________ You may leave the list at any time by sending the command SIGNOFF allstat to [log in to unmask], leaving the subject line blank.
