What is SAS Statistics
SAS statistics are driven by the SAS computer program which defines a sequence of operations that has to be performed on data that is stored as a table. Non-programmer Graphical user interfaces to SAS exist such as the SAS Enterprise Guide.
These GUIs are most often merely a front-end that automates or facilitates the generation of SAS programs.
The SAS components are intended to be accessed via an application programming interface, in the form of statements as well as procedural programming. SAS Assignment Help is provided by highly trained SAS experts in Statistics.
The SAS program has four major parts.
First is the DATA step. Second is the procedure step which contains everything that is not enclosed in a DATA step. The third is the macro language and a meta Programming language. Last is the ODS which is the Output Delivery System statement. This will direct any output or data sets created by DATA or procedure steps to any of the various file types. It can also apply styles and templates to the output.
Statistical Analysis of Data Using SAS Software
SAS Library Engines, as well as the Remote Library Services, allow access to data stored in external data structures and on remote computer platforms.
SAS program contains the DATA-step section which is similar to the Fourth-generation programming language such as SQL or focuses software. It assumes a default file structure, and it automates the process of identifying files in the operating system.
It opens the input file reads the next record, opens the output file, writes the next record, and closes the files. This allows the user/programmer to concentrate on the details of working with the data within each record.
So in effect, it will work almost entirely within an implicit program loop that runs for each record and any aspect of these Automated Functionalities may also be modified within the DATA step.

SAS will accomplish all other tasks by procedures that operate on the dataset as a whole. Typical tasks include printing or performing statistics. It may just require the user/programmer to identify the data set where the procedures are not restricted to only one behavior.
It will allow extensive customization which is controlled by mini-languages that are defined within the procedures. SAS also has an SQL procedure that allows the SQL programmers to use the system with no additional knowledge.
