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

● Operations Research and project Management

● Quality Improvement

● Application Development

● Data extraction

● Data transformation

● Data updation and modification

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.
