4. SAS
From traditional statistical analysis of variance and
predictive modeling to exact methods and
statistical visualization techniques, SAS/STAT
software is designed for both specialized and
enterprise wide analytical needs. SAS/STAT
software provides a complete, comprehensive set of
tools that can meet the data analysis needs of the
entire organization.

8. What Is SAS Enterprise Guide?
What Is SAS Enterprise Guide? SAS Enterprise Guide
is an easy-to-use Windows client application that
provides these features:
– access to much of the functionality of SAS
– an intuitive, visual, customizable interface
– transparent access to data
– ready-to-use tasks for analysis and reporting
– easy ways to export data and results to other
applications
– scripting and automation
– a program editor with syntax completion
and built-in function help

10. Create a Project for This TutorialIf SAS Enterprise Guide is not open, start it now. In the
Welcome window, select New Project.
If SAS Enterprise Guide is already open, select File >>
New Project. If you already had a project open in SAS
Enterprise Guide, you might be prompted to save the
project. Select the appropriate response.
The new project opens with an empty Process Flow
window.
www.kellytechno.com
11. 1. The Project TreeYou can use the Project Tree window to manage the
objects in your project. You can delete, rename, and
reorder the items in the project. You can also run a
process flow or schedule a process flow to run at a
particular time.
www.kellytechno.com
12. 2. Workspace and Process Flow Windows
You can have one or more
process flows in your project.
When you create a new project,
an empty Process Flow window
opens. As you add data, run
tasks, and generate output, an
icon for each object is added to
the process flow.
The process flow displays the
objects in a project, any
relationships that exist between
the objects, and the order in
which the objects will run when
you run the process flow.

13. 3. The Task List
You can use tasks to do
everything from manipulating
data, to running specific
analytical procedures, to
creating reports.
Many tasks are also available as
wizards, which contain a
limited number of options and
can provide a quick and easy
way to use some of the tasks.

14. Add SAS Data to the Project
You can add SAS data files
and other types of files,
including OLAP cubes,
information maps, ODBC-
compliant data, and files that
are created by other software
packages, such as Microsoft
Word or Microsoft Excel.
www.kellytechno.com
15. SAS Enterprise Guide requires all data that it accesses
to be in table format. A table is a rectangular
arrangement of rows (also called observations) and
columns (also called variables).
Name Gender Age Weight
Jones M 48 128.6
Laverne M 58 158.3
Jaffe F . 115.5
Wilson M 28 170.1

16. • a column's type is important because it affects how the
column can be used in a SAS Enterprise Guide task. A
column's type can be either character or numeric.
• Character variables, such as Name and Gender in the
preceding data set, can contain any values. Missing
character values are represented by a blank.
• Numeric variables, such as Age and Weight in the
preceding data set, can contain only numeric values.
Currency, date, and time data is stored as numeric
variables. Missing numeric values are represented by a
period.Name Gender Age Weight
Jones M 48 128.6
Laverne M 58 158.3
Jaffe F . 115.5
Wilson M 28 170.1 www.kellytechno.com
17. Local and Remote DataWhen you open data in SAS Enterprise Guide, you
must select whether you want to look for the data on
your local computer, a SAS server, or in a SAS folder.
www.kellytechno.com
18. Local and Remote Data (Cont’)
If you click My Computer, you can browse the
directory structure of your computer. You can open
any type of data file that SAS Enterprise Guide can
read.
If you click Servers, you can look for your data on a
server. A server can either be a local server if SAS
software is installed on your own computer, or it can
be a remote server if SAS software is installed on a
different computer.
www.kellytechno.com
19. Open Data from Server
Within each server there are icons that you can select for
Libraries and Files. Libraries are shortcut names for
directory locations that SAS knows about. Some libraries
are defined by SAS, and some are defined by SAS
Enterprise Guide. Libraries contain only SAS data sets.
The Files folder on a server enables you to access data files
in the directory structure on the computer where the SAS
server is running. For example, if you wanted to open a
Microsoft Excel file on a server that is defined in your
repository, you would use the Files node to locate and
open the file.
www.kellytechno.com
20. Open Data from SAS Folders
If you click SAS Folders, you can browse the list of
SAS folders that you can access. SAS folders are
defined in the SAS Metadata Server and can be used to
provide a central location for your stored processes,
information maps, and projects so that they can be
shared with other SAS applications. SAS folders can
also contain content that is not in the SAS Metadata
Server, such as data files.

21. Add SAS Data from Your Local Computer
• Select File >> Open >> Data. In the Open Data
window, select My Computer.
• Open the SAS Enterprise Guide samples directory and
double-click Data. By default, the sample programs,
projects, and data are located in
C:Program FilesSASEnterpriseGuide4.3Sample.
By default, all file types are displayed in the window.
Files with the icon are SAS data sets. Press CTRL
and select Orders.sd2 and Products.sas7bdat, and
then click Open.
www.kellytechno.com
22. Add SAS Data from Your Local Computer (Cont’)
Shortcuts to
the Products and Orders
tables are added to the
project, and the data sets
open in data grids.
By default, the tables open in
read-only mode. In this
mode, you can browse, resize
column widths, hide and hold
columns and rows, and copy
columns and rows to a new
table.
You cannot edit the data in
the table unless you change
to edit mode. Select Edit >>
Remove Protect Data
www.kellytechno.com
23. View the Properties of a Data Set
In the project tree, right-click Products and
select Properties from the pop-up menu. The Properties
for Products window opens. You can see information
about general properties such as the physical location of
the data and the date it was last modified.
www.kellytechno.com
24. View the Properties of a Data Set (Cont’)
In the selection pane, click Columns. Here you can
view a list of columns in your data and the column
attributes.
www.kellytechno.com
25. Add Data from a SAS Library
• Select File >> Open >> Data. In
the Open Data window,
select Servers.
• Double-click Libraries, and
then double-click SASHELP. As
you can see, only SAS data sets
are stored in libraries
• Scroll in the window and
double-click the PRDSALE data
set. A shortcut to the data is
added to the project and the
data opens in the data grid. www.kellytechno.com
26. Save the Project• Select File >> Save Project
As.
• The Save window opens and
prompts you to choose
whether to save the project on
your computer or on a server.
Select My Computer.
• In the Save window, select a
location for the project. In
the File name box, type ‘your
file name’. Project files are
saved with the extension .egp.
• Click Save.
