is Here how to get SAS to draw a scatterplot matrix. You need to
use the interactive data analysis module available through
menus.
Start up windowing SAS, as usual
Type in the appropriate data step commands to read your data; end
with a run; command.
Submit that data step to read your data into a data set. The log
window should tell you that the data set WORK.XXX was created with
NN observations and NN variables. XXX will be the name you gave the
data set (from data XXX;).
Find and click SOLUTIONS on the main menu (top of the SAS window). That drop
down menu includes ANALYSIS, click that. The third
pull down menu includes 'Interactive Data Analysis'. Select
that.
A new window will open up with two choice boxes labeled LIBRARY and
DATASET. Click WORK in the LIBRARY box. The data set box will then
include names the of your data set(s). Click on your data set name.
A new window will open up with a display of your data set. Click
and shift-click to select all the variables to be plotted.
The main menu at the top of the SAS window will now include
ANALYZE. Select that. One of the pull down menu options is
SCATTERPLOT. Select that.
SAS should now draw your scatterplot matrix in a new window.
You can print that plot. Make sure the window is highlighted, then
select FILE/PRINT. Click 'FILL PAGE' in the menu box that appears.
(otherwise each plot is on a separate page).
You may also be able to copy and paste the file into word.
For your homework a printout is perfectly adequate.
If you're a JMP user, a scatterplot is easy to get. Scatterplot
matrix is one of the choices under the Multivariate menu.
