How to Use SAS 9.1?
Once you have downloaded and installed SAS 9.1 for free on Windows 7, you can start using it to perform various data analysis tasks. There are different ways to use SAS 9.1, depending on your preference and skill level. You can use:
The SAS windowing environment, which consists of several windows that allow you to enter and edit SAS programs, view SAS output and log, browse SAS data sets, and access SAS tools and help.
The SAS Enterprise Guide, which is a GUI that provides point-and-click features, wizards, and menus to help you create and run SAS projects.
The SAS code editor, which is a text editor that allows you to write and run SAS programs using syntax highlighting, auto-completion, and debugging tools.
The SAS command line, which allows you to execute SAS commands and programs from a terminal window.
No matter which way you choose to use SAS 9.1, you need to follow some basic steps to perform a data analysis task:
Access your data source using the appropriate SAS product or procedure. For example, you can use the LIBNAME statement or the LIBNAME engine to assign a library name to a folder or a database that contains your data files. You can also use the IMPORT or EXPORT procedures to read or write data from external files such as Excel, CSV, or XML.
Manipulate and transform your data using the DATA step or the SQL procedure. For example, you can use the DATA step to create new variables, filter observations, merge or append data sets, or apply conditional logic. You can also use the SQL procedure to perform queries and joins on your data.
Analyze your data using the appropriate SAS product or procedure. For example, you can use the MEANS, FREQ, UNIVARIATE, or CORR procedures to perform descriptive statistics on your data. You can also use the REG, ANOVA, GLM, LOGISTIC, or PHREG procedures to perform inferential statistics on your data.
Present your results using the appropriate SAS product or procedure. For example, you can use the PRINT, REPORT, TABULATE, or ODS procedures to create tabular reports on your data. You can also use the GPLOT, GCHART, SGPLOT, or SGRENDER procedures to create graphical reports on your data.
Here are some examples of how to use SAS 9.1 to perform some common tasks:
Example 1: Importing Data from an Excel File
If you have an Excel file named "sales.xlsx" that contains sales data for a company, you can use the IMPORT procedure to read it into a SAS data set named "sales". You can also use the CONTENTS procedure to check the structure and attributes of the data set.
proc import datafile="sales.xlsx" out=sales dbms=xlsx replace;
run;
proc contents data=sales;
run;
Example 2: Creating a Summary Report
If you want to create a summary report that shows the average sales amount by product category and region for the sales data set, you can use the MEANS procedure with a CLASS statement and an OUTPUT statement. You can also use the PRINT procedure with a FORMAT statement and a WHERE statement to display only the relevant columns and rows.
proc means data=sales mean noprint;
class category region;
var amount;
output out=summary mean=avg_amount;
run;
proc print data=summary noobs;
format avg_amount dollar10.;
where _type_=3;
run;

Example 3: Creating a Scatter Plot
If you want to create a scatter plot that shows the relationship between sales amount and customer satisfaction for the sales data set, you can use the SGPLOT procedure with a SCATTER statement and a REG statement. You can also use an INSET statement to display some summary statistics on the plot.
proc sgplot data=sales;
scatter x=amount y=satisfaction / markerattrs=(color=blue);
reg x=amount y=satisfaction / lineattrs=(color=red);
inset "N"="n" "R-Square"="r
