SAS INTRODUCTION

      SAS

The SAS System is one of the most popular Statistical software for all kinds of data analysis. It is a general purpose statistical package designed for both interactive, non-interactive, and batch uses. 

SAS (Statistical Analysis System) software is comprehensive software which deals with many problems related to Statistical analysis, Spreadsheet, Data Creation, Graphics, etc. It is a layered, multivendor architecture. Regardless of the difference in hardware, operating systems, etc., the SAS applications look the same and produce the same results. The three components of the SAS System are Host, Portable Applications and Data. Host provides all the required interfaces between the SAS system and the operating environment. Functionalities and applications reside in Portable component and the user supplies the Data. We, in this course will be dealing with the software related to perform statistical analysis of data.

      Windows of SAS

• Program Editor : All the instructions are given here.

• Log : Displays SAS statements submitted for execution and messages

• Output : Gives the output generated

      Rules for SAS Statements

• SAS program communicates with computer by the SAS statements.

• Each statement of SAS program must end with semicolon (;).

• Each program must end with run statement.

• Statements can be started from any column.

SAS Interview Questions

 SAS Interview Questions
 
    What is SAS ?

The term "statistical analysis system" is used to refer to software that allows the user to perform statistical analysis on data sets. Another commonly-used term for this type of software is statistical programming language. When capitalized, Statistical Analysis System (SAS) is also the proper name of one of the most well-known software packages of this type.

     How to use SAS ?

A statistical analysis system provides the automation and processing power needed to facilitate the manipulation and analysis of data sets. These packages facilitate computation of both descriptive and inductive statistics. Commonly-used descriptive statistical computations include calculation of central tendency, frequency distribution, and association. Inductive statistical analysis that can be performed with a statistical analysis system includes statistical hypothesis testing, such as the t-test, the z-test, and the chi-square test. Many statistical analysis systems also support other tests, such as analysis of variance (ANOVA) and its relatives, and various types of regression testing.

      Where to use SAS ?

Statistical analysis systems are used in a wide variety of settings. Natural and social scientists in academic and commercial research settings are the most frequent users of these types of software packages. Businesses may also use a statistical analysis system for operations research, project management, and other business intelligence applications.

     Will customers have to migrate their 9.1.3 content to be compatible with 9.2 ?

If a customer is upgrading to 9.2 Phase 1 (the core SAS products...category A under the HHS ELA), there is no migration process required. However, starting with the 9.2 phase 2, customers will need to migrate their 9.1.3 metadata content to be compatible with the 9.2 architecture. With SAS 9.2 phase 2, the metadata infrastructure, the folder structure, the security model, and the SAS directory structure have been significantly enhanced, resulting in changes to object content and formats. SAS has created a set of tools that help customers deploy a 9.2 environment and migrate or promote their content.

     Are all operating systems supported for SAS 9.1.3 supported for SAS 9.2 ?

No. SAS 9.2 is not supported on Tru64, Open VMS for Alpha, Linux on Itanium, or Windows NT/2000.

    Are there any new operating systems that will now be supported at SAS 9.2 ?

Yes. SAS 9.2 has added support on Windows x64, Linux x86-64, and Open VMS on HP Integrity (Itanium). Support for Solaris 10 x64 will be extended across the platform for EBI Server and DI Server, including mid-tiers.

    Will SAS 9.2 be supported on Vista, and will SAS 9.2 work with Microsoft IE 7 ?

SAS is committed to supporting business versions of Microsoft Vista (Business, Enterprise, and Ultimate). The foundation SAS technologies are supported on Vista (32-bit editions only) in SAS 9.1.3SP4, but not the client applications. IE 7 is also supported in SAS 9.1.3SP4, but only on Windows XP Pro SP2. SAS 9.2 will also be supported on Vista (for 32 or 64-bit editions). SAS 9.2 platform client applications will support Vista and IE 7 on Vista, starting with phase 2. Consumer editions of Vista (Home Basic and Home Premium) are not supported.

    Can you run SAS 8 and SAS 9 together ?

Yes. SAS 9 is installed in a separate file system directory.

    If a customer uses the Enterprise Guide 4.1 client with foundation tools on a server, will they have to wait until Phase 2 when Enterprise Guide 4.2 is released, or can they continue using the Enterprise Guide 4.1 client and upgrade to SAS 9.2 on the server ?

It depends. Enterprise Guide 4.1 (current release) will work in conjunction with a local SAS 9.2 installation.

   If a customer uses EG client with foundation tools on a server, will they have to wait until EG 4.2 is released or can they continue using EG 4.1 and upgrade to 9.2 on the server ?

To answer this lets break the scenarios down to 4 questions and answers:

• Will EG 4.1 (today's release) work in conjunction with a local SAS 9.2 installation -- Yes.

• Will EG 4.1 (today's release) work in conjunction with a phase 2 SAS 9.2 remote installation -- No.

• Will EG 4.2 work with a SAS 9.1.3 local installation -- No.

• Will EG 4.2 work with a SAS 9.1.3 remote installation -- No.

     Will a new SID be required for SAS 9.2 software ?

Yes. The SID file is posted on the iSDP website with the software. Only designated iSDP reps can access these files. To contact a designated iSDP rep for your IC/Agency, please view the Contact Lookup or contact the NIH Help Desk.

     Are there some products within Category A that will not ship initially with 9.2 ?

Yes. They include Enterprise Guide (see explanation above), Integration Technologies, Online Tutor, Enterprise Reporter, App Dev Studio, Access to R3, Access to People Soft and Access to BAAN.

    Is a new 9.2 plan file required, or can the 9.1.3 plan file be re-used ?

A new 9.2 plan file is required. There is a standard plan file that can be used for the foundation products that comes with the software.
