No experience with SAS is assumed, but students should be familiar with computing in the Windows environment. A basic understanding of statistical and epidemiological principles is strongly encouraged but brief introductions to key concepts will be offered as necessary although focus will naturally be on the application and interpretation of statistical and epidemiological concepts in the context of SAS.
Students will need access to a computer with high-speed internet access and SAS software version 9.0 or higher installed. At minimum, Base SAS and SAS/STAT should be installed. Please read “Obtaining and installing SAS” below for helpful tips on acquiring and installing SAS software.
Obtaining SAS Software
Please find information below regarding various approaches to installing SAS. Please note that these are general guidelines that have worked well for students in previous years. However, these instructions might not work for all students and we cannot offer technical assistance for SAS installations. It is the responsibility of registrants to obtain access to SAS software prior to the beginning of this course.
SAS for FREE on a Mac or PC
See below for details regarding the use of SAS University Edition, a free SAS product for teaching and research. Be aware that the SAS University Edition can be slow compared with a full SAS installation. If at all possible, it is strongly recommended that registrants gain access to a full SAS installation (more details below).
Purchasing and Installing SAS
For non-Columbia registrants, SAS can be ordered by contacting SAS customer support: http://www.sas.com/technologies/analytics/statistics/stat/index.html#section=1
It is also recommended that non-Columbia registrants check to be sure that free or discounted versions of SAS are not available for purchase through their respective institutions (e.g., many universities have negotiated reduced licensing fees for SAS).
Columbia students, staff and faculty can obtain licenses and installation disks through CUIT. Please see the following link for details:
Installing SAS Software
Please find below, a guide for purchasing and installing SAS on a personal computer. Note that this information is meant as a guide and should not replace a careful reading of the installation instructions provided by SAS. Note that we are unable to offer any technical support for acquiring or installing SAS software.
1. Both 32-bit and 64-bit versions of SAS 9.3 and 9.2 are available for Windows 7, and Vista Operating Systems. Be sure you purchase the version of SAS that is compatible with your operating system.
- For Windows OS 7, you can determine if you have a 32-bit or 64-bit OS by going to the Windows start menu and selecting “Control Panel”, then “System and Security”, then “System”. A summary of your Windows OS type will be displayed under “System”.
2. To the best of the instructor's knowledge, SAS is not compatible with Windows Home versions; you must be running Windows Professional, Enterprise or Ultimate.
- For Windows OS 7, you can find this information by going to the Windows start menu and selecting “Control Panel”, then “System and Security”, then “System”. A summary of your Windows OS edition will be displayed under “Windows edition'.
- Columbia students, faculty and staff can download a free Windows OS 7 Enterprise edition from CUMC-IT at the following link: http://cuit.columbia.edu/cuit/software-downloads/operating-system-software/windows-7-enterprise
Current versions of SAS are not available for Mac computers. Nevertheless, it is quite possible to use SAS on a Mac. Several faculty in the department of Epidemiology at Columbia University run SAS on Mac, including the course instructor. There are various approaches to getting SAS on a Mac but the following is recommended:
1. Install a virtualization software on your Mac. A virtualization software allows the user to install a nonMac operating system on their Mac computer that can run simultaneously with their Mac OS. This does not change the look or function of your Mac computer. Two options are listed below. The course instructor has had good success with Parallels although VM Fusion seems to work well also.

2. Install Windows 7 Enterprise OS as a virtual machine via either Parallels or VM Fusion (see part 1 above).
- Columbia students, staff and faculty can download a free Windows OS 7 Enterprise from CUMC-IT at the following link: http://cuit.columbia.edu/cuit/software-downloads/operating-system-software/windows-7-enterprise
3. Start your Windows 7 OS and install SAS on your Windows 7 OS.
