Software Information

The following software is available at no charge, or nominal charge, for use in certain courses. Please note that the instructor may provide illustrations, examples, exercises and occasional pointers in a particular software package with which he/she is familiar, but his/her role is not to serve as a help desk for the software. Where possible, teaching assistants have provided supplemental examples in other packages, and will provide feedback on student work in a variety of software packages. Please check the course description page for details about how software is supported in each course.

IMPORTANT! For free trial versions, check the duration before installing, and don't install the software too early -- make sure that the free trial will run until the end of the course. For a 30-day trial, this generally means you should wait until at least the first week of the course. Once the course opens, you can review information about assignments and due dates to be sure that your installation will carry you as long as needed.

MAC USER: Please note that, in most cases, statistical software differs in the capabilities that are available on the Mac, and, in some cases is not available at all on the Mac (or on the most recent Macs). If you are a Mac user, please check first to be sure that the software/capabilities you are interested in are available.
