SAS is a statistical analysis software. I t was created by the SAS Software Institute in 1960. F rom January 1, 1960, SAS was used for data management, business intelligence, predictive analysis, descriptive and normative analysis, etc. S ince then, many new statistical programs and components have been introduced in the software.

By introducing JMP (Jump) statistical SAS took advantage of this graphical user interface introduced by Macintosh. J umps are basically used in applications like Six Sigma, Design, Quality Control, Engineering and Scientific Analysis.

SAS is cross-platform, which means you can run SAS on any operating system Linux or Windows. S AS is a data analysis report performed by SAS programmers using several sequences of SAS dataset operations.

Over the years, SAS has added a large portfolio of solutions and products. W ith solutions for data governance, data quality, big data analytics, text mining, fraud management, and health science, we can safely assume that scenarios use SAS solutions to serve every business area.

If necessary, you can access the SAS component product list.

Why do we use SAS?

It is mainly used in large data sets. W ith the help of SAS software, you can perform various operations on similar data:

  • Data management
  • Statistical analysis
  • The formation of the report with perfect graphics
  • Business plan
  • Operations planning and management projects
  • Quality improvement
  • Application development
  • Extracts
  • Data transformation
  • data and choose to update the retrofit

SAS has more than 200 components.

SN SAS components and their usage
1 SAS base
This is a core component that includes data management facilities and programming languages for data analysis. It is also the most widely used.
2 SAS / GRAPH
Create charts that demonstrate a better understanding and presentation of the results in the appropriate format.
3 SAS / STAT
Statistical analysis with variance analysis, regression, multivariable analysis, survival analysis and psychoanalyt analysis, mixed model analysis.
4 SAS / OR
Action investigation.
Five SAS / ETS
Econometrics and time series analysis.
6 SAS / IML
CInteractive matrix language.
7 SAS / AF
Application facilities.
8 SAS / QC
Quality control.
9 SAS / INSIGHT
Data mining.
10 SAS / PH
Clinical trial analysis.
11 SAS / Enterprise Miner
Data mining.

SAS software type

  • Windows or PC SAS
  • SAS EG (Enterprise Guide)
  • SAS EM (Predictive Analysis of Enterprise Miner's Internet Explorer)
  • SAS means
  • SAS statistics

Window SAS is typically used by organizations and training institutions. S ome organizations use Linux but don't have a graphical user interface, so you have to write code for each query. B ut there are also many utilities available at Window SAS that can help programmers a lot, which also reduces code writing and time.

Window SAS consists of five parts.

SN Windows SAS and their usage
1 The log window
The log window is like an execution window, and we can check the execution of the SAS program. I n this window, we can check for errors too. A fter you run the program, it is important to check each log window. This way we can see if the program is executing correctly.
2 The editor window
The editor window is part of SAS and we write all the code. It's like a note book. . .
3 The output window
The output window is the result window, where we can see the output of our program.
4 The result window
It is like an index to all outputs. A ll the programs we've run at a meeting in SAS are listed there and you can open the output by clicking on the output. H owever, these were only mentioned at one SAS meeting. If we close the software and then open it, then the result window will be empty.
Five Browse the window
All libraries listed here. You can also browse the files supported by your system SAS from here.

SAS library

The SAS is stored in the library. Y ou can create a library and save all similar plans in the library. S AS provides you with the facilities to create multiple libraries. T he SAS logic library is only 8 characters long.

SAS has two types of libraries:

SN Windows SAS and their usage
1 Temporary library
This is the default library for SAS. A ll of this, if we create a program that does not select another library, will be stored in the temporary library by default. Y ou can check this gallery in the browse window. I f you create an SAS program and any permanent libraries, the program will be lost if you do not store the program in a permanent library before you close or restart SAS. The program should only run in the library.
2 Permanent library
This is the permanent library of SAS. W e can create a new SAS library by using the SAS utility or by writing code in the editor window. These libraries are named permanent, and if we create an SAS permanent library, the programs stored in the libraries will be used permanently.
