SAS gives you excellent data management capabilities
1)Subset Data
2)Create Variables

SAS is the gold standard for statistical
analysis.
After Data Management the next step is data analysis :

2)Summary reports
1)List reports
Once you have analyzed data you can present it better with SAS

SAS Programming Language

SAS Programming Process
Define business problem
Write a SAS program
Run the program
Review the results
Debug or modify

SAS programming is based on two building blocks:
1)DATA Steps
DATA steps create or modify SAS data sets. Using DATA steps you can:
• Add data to a data set
• Compute values of variables
• Create new data sets (by sub-setting, merging)
SAS Program Structure

SAS programming is based on two building blocks:
2)PROC Steps
PROC steps analyse and process SAS data sets. Using PROC steps you can:
• Print a report
• Produce descriptive analysis
• Create a tabular report
• Produce plots and charts

SAS Data
Variables
Observations
Data is central to every data set.
• In SAS Data is in tabular form
• Variables occupy the columns
• Observations occupy the rows
Data types:
• Numeric
• Characters

SAS Data – Informat
Informat
• Informats tell SAS how to read a variable
• Every variable in any SAS dataset will have an informat.
• There are three main classes of informats: character, numeric and date.
Type Informat Name What it does
Character $w. Reads character data of length w
Numeric w.d
Reads numeric data of length w with d
decimal points
Date MMDDYYw. Reads date data in the form MM-DD-YY

SAS Data - Format
Format
• Formats tell SAS how to display the values in the variable.
• Formats can be grouped three classes (character, numeric, and date-time)
• The general form of a format statement is:
FORMAT variable-name FORMAT-NAME.;

SAS Data - Date
• Dates in SAS are represented in a special way.
• SAS date = number of days since January 1, 1960.
Date SAS Date Value
January 1, 1959 -365
January 1, 1960 0
January 1, 1961 366
January 1, 2003 15706

A SAS program should follow below mentioned rules:
1)Almost every code
begins with a DATA or a
PROC Step
2)Every line of SAS code
ends with a semi colon
3)A SAS code ends with
RUN or QUIT keyword

Linear Regression
SAS Program
• Establish a relationship between two variables
• Forecast a new observation
Ex: 1) Income and spending
2)Student height and grades
Y = B0 + B1*X
Intercept
Slope
H(0) : B1 = 0 (X and Y are not related)
H(1) : B1 != 0 (X and Y are related)

;
proc print;
run;
1) Create a sample data set

SAS Program
2) View Scatter Plot
proc sgscatter data = practice1;
plot x*y;

SAS Program
3) Run linear regression model
proc reg data = practice1;
model y = x / clb;
run;

SAS Program

SAS Program
4) Create and add new value of x to predict corresponding y
data practice2;
y = .; x = 8.5;
proc print;
run;
data practice1;
set practice1 practice2;
proc print;
run; New value

SAS Program
5) Predict the value of y using the model
proc reg data = practice1;
model y = x/cli;
run;

SAS Applications

SAS Applications
1)Stock Prediction 2)Create Safe Drugs
3)Fight Fraud 4)Optimize Workflow
