SAS

From Waisman Brain Imaging Wiki

SAS is a statistical analysis computer language. It is very powerful, but can be quite fussy and difficult to use. Many labbies now opt for SPSS instead, as it is Windows-based, easy to program in, and much easier to import data into. However, SAS still has one clear advantage: it can handle enormous data sets (and is thus run on the labs' brawniest servers). There is still a lot of lab code floating around for analysing EEG data in SAS. If you're interested in using SAS, talk to Larry or Corrina; they may be able to help you get started.

If you're interested in re-analyzing data from old studies that were collected using the HEM/SCS systems and were stored on the VMS servers, you'll likely need to learn SAS, as all of the data analysis on those studies was done in SAS.

A good introduction to SAS is The Little SAS Book (http://www.amazon.com/exec/obidos/tg/detail/-/1590473337/qid=1127856028/sr=8-1/ref=pd_bbs_1/102-8625379-2485702?v=glance&s=books&n=507846). There are copies floating around the labs.

SAS is produced by The SAS Institute (http://www.sas.com/).

Our Tips & Tweaks

  • Note that at Brogden, we've made the decision to discontinue our SAS LINUX licenses, due to recent underuse. We'll continue to run SAS version 8 on LAN104. If you need to use SAS at Keck, please talk to Adrian. Given the labs' shift towards SPSS, it is probably best to use that if you're just starting out on your statistical analysis.
