SQL includes operators and functions for calculating values on stored values. SQL allows the use of expressions in the select list to project data, as in the following example, which returns a list of books that cost more than 100.00 with an additional sales_tax column containing a sales tax figure calculated at 6% of the price.
[15] [16] PROC SQL can be used to work with SQL syntax within SAS. [17] Users can input both numeric and character data into base SAS. SAS statements must begin with a reserved keyword and end with ; [18] but the language is otherwise flexible in terms of formatting and most statements are case insensitive. [19]

Somers’ D plays a central role in rank statistics and is the parameter behind many nonparametric methods. [2] It is also used as a quality measure of binary choice or ordinal regression (e.g., logistic regressions ) and credit scoring models.
In statistics, ranking is the data transformation in which numerical or ordinal values are replaced by their rank when the data are sorted. For example, if the numerical data 3.4, 5.1, 2.6, 7.3 are observed, the ranks of these data items would be 2, 3, 1 and 4 respectively.
SAS introduced new features through dot-releases. From 6.06 to 6.09, a user interface based on the Windows paradigm was introduced and support for SQL was added. [39] Version 7 introduced the Output Delivery System (ODS) and an improved text editor. Subsequent releases improved upon the ODS. For example, more output options were added in version 8.
For example, multiplication is granted a higher precedence than addition, and it has been this way since the introduction of modern algebraic notation. [ 2 ] [ 3 ] Thus, in the expression 1 + 2 × 3 , the multiplication is performed before addition, and the expression has the value 1 + (2 × 3) = 7 , and not (1 + 2) × 3 = 9 .
