1 Introduction. Modules SAS The SAS (Statistical Analysis System) is a modern system of information processing developed by SAS Institute since 1974 in the past was mainly used for the analysis of statistical data. Present the shape of a team of multiple modules, with a very wide range of applications and easy to use manner. The ACC Cyfronet AGH version 9.3 of the SAS System is on an IBM HS21 Mars and includes the following modules: Base SAS - basic module of the SAS, must always be installed, includes, among others, procedures for operations on data SAS / ASSIST - generator programs and a graphical interface to the SAS, facilitates writing programs that are created automatically when you run a complex system of menus SAS / GRAPH - graphical tools for presentation and analysis of data, allows you to create color and black-and-white charts, program listings, maps SAS / FSP - interactive environment for data input and editing SAS / AF - interactive application development environment, allows you to create user-friendly application that does not need to know the SAS system (however, these applications can only be performed by SAS, it is not possible to create an independent object code) SAS / STAT - advanced statistical analysis, contains many well-tested statistical procedures (regression analysis, analysis of variance, and others) SAS / INSIGHT - interactive statistical analysis, the results of the statistical analysis are presented in graphic form, it is possible to interactive data manipulation SAS / LAB - support tools and the statistical laboratory testing and engineering analysis of lead is led by the program SAS / IML - an interactive matrix language (Interactive Matrix Language) for data manipulation, contains many mathematical operators and matrix SAS / OR - tools of operations research, optimization, project management, mathematical programming SAS / ETS - tools of forecasting, econometric modeling, time series analysis and financial planning SAS / QC - enhancement techniques (design of experiments, analysis of quality) On your computer, Mars SAS system version 9.3 is located in /opt1/sas/SASFoundation/9.3. Samples subdirectory contains sample programs. In addition to the modules installed in us, yet distributes SAS Institute, among others: SAS / EIS used for the construction and operation of information systems for business management. SAS / ACCESS is a few modules to communicate with external databases such as ORACLE, INGRES, SYBASE, Informix, DB2, SQL Server SAS / ACCESS to PC File Formats to access the files in the DBF, DIF, XLS, WK1, created by programs and spreadsheets PC SAS / CONNECT is a module that allows cooperation SASowych systems in client / server architecture, the data can then be shared between computers and the programs created on one computer can be sent to perform on another SAS / CALC is the spreadsheet SAS / GIS is a system of geographic information processing, enabling analysis of spatial data SAS / PH-Clinical provides tools for the pharmaceutical industry to help with research into new medicines SAS / SHARE enables simultaneous data access for multiple users The offer SAS Institute include comprehensive tools such as: SAS Data Warehouse is a software package that facilitates the creation and use of the data warehouse SAS Enterprise Miner is a product used for analytical exploration of the data (Data Mining) SAS Enterprise Reporter is an application designed for reporting and analysis of data from different databases and spreadsheets Risk Vision is an application supporting risk management For more information about the SAS system and its modules can be found in ksążkach listed in the bibliography, as well as on the websites: http://support.sas.com/documentation/onlinedoc/index.html. On the Internet, visit www.sas.com page, which includes information about products, organized conferences, user groups, as well as the many programs provided by their creators. Polish subsidiary of SAS Institute is located in Warsaw, ul. Dawn 17, tel. (22) 873 9200. 2 Working with the SAS The SAS can work interactively only in graphical mode (using the UNIX X Window). Graphical terminal (X-terminal or workstation) causes SAS sas command. Do not forget to earlier, appropriate system variable DISPLAY is set so as to point to our terminal or workstation: ssh mars.cyfronet.krakow.pl ssh mars55 setenv DISPLAY <name-terminal>: 0 add SAS module sas In addition to working in interactive mode, SAS can also work in batch. Ability to work batch is valuable especially when performing long calculations that exceed the limit calculation time appointed for interactive tasks on the computer. Execution of our program in a batch script might look like this: sas example1 przyklad1.sas is a file with a program written in SAS, located in the current directory.
SAS means Statistical Analysis System. Historical Data Analysis using some specific algorithms/statistical methods.
