STAT430 Lecture 1: Introduction to SAS
What is SAS?
SAS stands for Statistical Analysis Software. It was created in the year 1960 by the
SAS Institute. From 1st January 1960, SAS was used for data management, business
intelligence, Predictive Analysis, Descriptive and Prescriptive Analysis etc. Since then,
many new statistical procedures and components were introduced in the software.
With the introduction of JMP (Jump) for statistics SAS took advantage of the Graphical
user Interface which was introduced by the Macintosh. Jump is basically used for the
applications like Six Sigma, designs, quality control and engineering and scientific
analysis.
SAS is platform independent which means you can run SAS on any operating system
either Linux or Windows. SAS is driven by SAS programmers who use several
sequences of operations on the SAS datasets to make proper reports for data analysis.
Over the years SAS has added numerous solutions to its product portfolio. It has
solution for Data Governance, Data Quality, Big Data Analytics, Text Mining, Fraud
management, Health science etc. We can safely assume SAS has a solution for every
business domain.
Why do we use SAS?
SAS is basically worked on large datasets. With the help of SAS software you can
perform various operations on the data like:
Data Management
Statistical Analysis
Report formation with perfect graphics
Business Planning

If we talk about the components of SAS then more than 200 components are available
in SAS.
Base SAS-It is a core component which contains data management facility and a
programming language for data analysis. It is also the most widely used.
SAS/Graph-Create graphs, presentations for better understanding and
showcasing the result in a proper format.
SAS/STAT-Perform Statistical analysis with the variance analysis, regression,
multivariate analysis, survival analysis, and psychometric analysis, mixed model
analysis.
SAS/OR-Operations research.
SAS/ETS-Econometrics and Time Series Analysis.
SAS/IML-CInteractive matrix language.
SAS/AF-Applications facility.
Type of SAS software
Mostly we use Window SAS in organisation as well as in training institute. Some of the
organisations use Linux but there is no graphical user interface so you have to write
code for every query. But in window SAS there are a lot of utilities available which helps
the programmers very much and it also reduces the time of writing the codes as well.
There are 5 parts to a SAS window.
