Statistical Analysis System Company has continuously developed business data analysis and prediction technology with all walks of life. Its important application fields include government economic decision-making and enterprise decision support applications. It has become the fifth largest software company in the world.
The statistical analysis system software is used forDecision supportHowever, the earliest function of the software system was limited to statistical analysis;So far, the statistical analysis function is still its important module and core function.At present, the latest version of the statistical analysis system is 9.4.
After years of development, the statistical analysis system has spread all over the world, and the units used are all over the fields of finance, medicine and health, production, transportation, communication, scientific research, government and education;In the field of data processing and statistical analysis, the statistical analysis system is known as the "Big Mac" in the statistical software industry.[1]
Module Introduction
Announce
edit
The statistical analysis system is a module software system, which is composed of multiple functional modules. The description of relevant software modules is as follows:
BASE
It is the core module of the statistical analysis system.Provide file establishmentData retrieval, management, analysis and presentation.
SAS/ASSIST
The software is a menu type user interface module.It can use various application tools provided by the statistical analysis system to execute the functions of each module in the way of menu selection instead of writing programs.
SAS/CONNECT
It is a collaborative and decentralized processing module.It provides the ability to link the statistical analysis systems of different platforms, enabling the system to achieve data integration and resource sharing.
SAS/GRAPH
To make high-resolution color graphics module.It can be used to generate statistical charts of various colors and types, such as column chart, pie chart, point chart, three-dimensional chart, contour map and map, etc.
SAS/ETS
An application system development tool used to develop and maintain the Executive Information System.Provide time series reading, analysis, prediction and establishmentEconometricsModel and other functions.
SAS/AF
Application system development tools.utilizeObject-oriented programAnd graphical user interface to open the application system.It is convenient for users to use the functions in SAS.
SAS/FSP
Data conversation tool for graphical user interface.Graphical interface is used as data login, editing, retrieval and query functions.
SAS/ACCESS
It is used to link and convert data with database software.The database software that provides the connection is ORACLEIBM DB2, MS ACCESS, DBASE, SYBASE, MS SQ, SERVER, etc.
SAS/STAT
It is a tool for comprehensive statistical analysis methods.Provided asregression analysis、ANOVA、Category analysis、Multivariate analysis, cluster analysisSurvival analysis, PSYCHOMETRICANALYSIS andNonparametric analysisIt also has the function of variable conversion such as normalization, linearization and non linearization.
SAS/LAB
A tool for data analysis in a guided manner.It provides statistical assumption analysis, such as OUTLIER, NORMAL, SCALING conversion and other functions, and can assist in making conclusions. Moreover, it can store all execution processes for future analysis or report reference.
SAS/EIS
Application system development tools.Unlike SAS/AF, this module does not require interface development, but only defines relevant data.
SAS/IML
It is a conversational higher-order matrix language tool.It provides high-level scientific, engineering and statistical applications, and has the function of graph generation and data display.
The latest 9.3 version also supportsfree software Statistical software planR LanguageThrough its SAS/IML module, it can be connected to each other for limited use. However, if you want to use each other, you must install R language software in the same computer in the SAS system.At present, relevant functions are supported as follows:
Data format conversion between two softwares: calling and using R language function;The analysis results in R language are transmitted to SAS.
SAS/QC
It is a tool for statistical quality control.It is used for process analysis, experimental design and other functions. It is convenient for users to get results quickly through menu interface.
SAS/OR
It is a decision support tool.For plan management, linear andnonlinear programmingAnd resource optimization allocation.
SAS/GIS
It is the graphic system of geographical data.
SAS/WebAF
A graphical interface development tool like SAS/AF.It is mainly used for the user interface developed on the Web.[2]
SAS client related software

Enterprise Guide software
Since about 2000, SAS has provided a new client software, Enterprise Guide, which can provide a visual operation interface to facilitate users to operate applications and reduce the threshold of statistical analysis.The software has the following main functions:
one
Intuitive and visual user interface can be customized, but it is different from SAS/AF or SAS/WebAF
two
More secure access to original data to facilitate user rights management of the database
three
The analysis data is edited in a process way, which can lower the threshold for users
four
Relevant programs can be classified into analysis, report, chart, query, etc
five
Support automatic scheduling and related script generators
six
However, it can still support programs edited with code
When the SAS Enterprise Guide is used, it is mutually supported and used with the original SAS (that is, Base SAS) software.The purpose of SAS Enterprise Guide is similar to the above key points. For example, EG is used as the user interface to generate related routines or programs, which are sent to SAS (Server/Client) for processing and execution. The final results are still returned to the EG interface for the convenience of users, that is, the mode of EG>SAS (Server/Client)>EG.
Because the software is not completelyC languageTo write, but to useJavaAndC#Used together. If EG software is required, at least install it.NET FrameworkAfter installationJRE(that is, the Java SDK runtime version 1.4.1) runtime environment suite.[2]
JMP software
Its reading is the same as that of Jump, a subsidiary of Statistical Analysis SystemJMPIt was published in 1989. It was originally a high-level statistical analysis software used on the Mac system, and later it was successively produced for Windows and Linux. At present, the latest version is 9.0 (Sep 2010).In addition to the original statistical analysis of the software, the higher-order "parametric" graphic display analysis and application of statistical models can achieve further data analysis by changing relevant parameters;Its software is also provided withMicrosoftExcelThe use of component add ins provides a closer combination of JMP and Excel, and also allows Excel to break through the use limit on the data sheet.[2]
