Information on SAS
This document contains information about using SAS on our system.
Some is specific to our implementation, but most is quite general.
SAS is a product of SAS Institute
Inc., Cary, NC. If you have questions about SAS courses or about
how to get help on SAS, please contact SAS directly. These pages
provide local information that might be of broader use.
Return to U WI Statistics Computing Facilities
Note: SAS 6.10 is now available on our bayes computer.
To use it, you must add /s/sas/bin to your PATH.
This would usually be done in the file ~/.cshrc.local or
in ~/.profile, depending on the shell that you use.
Here is a possible setup for ~/.cshrc.local:
set path = ($path /s/sas/bin)
[Some peculiarities with AFS require SAS calls to use the options as
% sas -filelocks none yourfile.sas
This is now automatically performed. If you had set up an alpha.sas
alias in your .cshrc.local file, you may now remove it.]
The SAS version 5 (1980s) and 6.0.3 (roughly 1989) manuals (see books below) are adequate for 75% to 90%,
respectively, of SAS commands. [Earlier versions should be discarded.]
However, many improvements and several
important new procedures have been included in the 6.0.7 (roughly
1992) and 6.0.9 (1994-5) versions.
The big new thing in SAS version 6.0.7 is the Insight module. This
lets you do exploratory data analysis. 3-d point clouds with
rotation. Brushing a value in one window and seeing it highlighted in
another dimension. It is much closer to the type of windowing
interaction one would like to see. However, many still prefer to use
SAS in "batch mode", submitting a file of commands.
Still more improvements are in version 6.0.9, including
- proc genmod - generalized linear models
- proc lifetest - Kaplan-Meier plots and nonparametric tests of
survival curves
- proc logistic - logistic regression
- proc mixed - mixed effects models
- proc phreg - proportional hazards regression
There is also a proc glmmod which offers a model-building front
end to proc glm
which may be of interest as well.
We should have 6.0.9 by the end of 1994. These are described in
Technical Bulletins P-229 and P-243.
Walt Stroup, U NE Lincoln, is writing a book
about proc mixed which should be out in 1995.
See also SAS on Our Bayes Computer above.
There are several recent books about SAS.
Milliken & Johnson provides a comprehensive tour of linear models,
with a lot of reference to SAS. DiIorio & Hardy seems a good all-around
introductory reference. Mason's book also comes well recommended.
- Cody RP & Smith JK (1991)
Applied Statistics and the SAS Programming Language,
3rd ed, Prentice Hall.
[Seems a nice but very light introduction.
Some will find it does not go far enough.]
- DiIorio FC & Hardy KA (1996)
Quick Start to Data Analysis with SAS,
Duxbury.
[Fairly comprehensive introduction.
Beyond basics of data handling.
Introduces many common statistical procedures by example,
but somewhat uneven in their detail.]
- Jaffe JA (1989)
Mastering the SAS System,
van Nostrand Reinhold
(629pp, $45).
[OK but not comprehensive.]
- Mason P (1996)
In the Know... SAS Tips & Techniques From Around the Globe,
SAS Institute Inc. #55513
- Milliken GA, & Johnson DE (1984)
Analysis of Messy Data vol. 1: Designed Experiments.
Chapman & Hall.
[Nice detail for more advanced researcher; recommended for
Stat 850 students.]
SAS Institute Inc., Cary, NC,
has a wide array of material, some available locally
(e.g. at
DoIT Showroom & Solutions).
They can be ordered via the web from the
SAS Publications Catalog.

- Littell, Milliken, Stroup and Wolfinger (1996)
SAS System for Mixed Models.
Ideal supplement for the last half to third of the course.
Describes proc mixed usage in great detail with examples.

SAS System for Linear Models, 3rd ed.
Practical guide for many designs considered in this course. This
package is used widely in government and industry, as well as academia.

- Recent New Procedures in SAS (after 6.0.7):
The SAS System for ... books are quite good, and very
self-contained. Dedicated researchers should consider the SAS/STAT
guide, which has many examples showing the power of the system.
The language guide gives an overview and
details on the data step, including transformation functions.
The intro is not needed; the procedures guide overlaps somewhat with SAS/STAT.
Version 5 manuals can be used for the current release [SAS User's Guide for
Basics (#P5603 $24.95) and for Statistics (#P5604 $22.95)], as can manuals for
the PC version [Introduction #P5710 $12.95, Language #P5856 $19.95, SAS/STAT
#P5639 $25.95]. However, some commands may have changed--be alert!
JMP
is an interactive statistical analysis and data exploration
system from SAS Institute Inc. It has been available
on the Mac for some time now and will soon be out
under Windows.
In addition to pull-down graphics,
JMP
has a nice design component.
However, its graphing functions can be very limiting
(displaying the data is good but plotting the data for
output graphs is poor).
There is no "scatter needle" plot option as there is in DeltaGraph.
But it is possible to change the axes in the rotating
3-d scatter plot so that the plot appeared the same as it did in
DeltaGraph.
That way - individual points around the periphery can be easily
pinpointed with JMP.
The JMP-L List Server is up!
The list is for discussions and reports of interest to JMP users.
Subscription is open; discussion is unmoderated.
