Loops allow you to execute SAS statements repeatedly thereby reducing the number of code lines.
The flow in loops can be classified as entry controlled or exit controlled. If the programming compiler checks for all conditions associated with the beginning of the loops executions are validated and true, then it is called as Entry controlled loops.
One of the major strength of SAS is its ability to work with character data. The collection of functions and call routines are discussed in this tutorial.
SAS date and time are one of the important topics in SAS due to the fact that SAS date and time have unique characteristics. SAS dates are not numeric not character variable, when displayed it resembles character but it is stored as a number. SAS date begins from January 1, 1960, and has a value of 0. Prior to this date are negative numbers and those after this date are positive numbers. SAS Formats are used to display values in various formats. There is a number of different SAS date formats which you can apply and make the dates readable.
SAS formats are the instruction that specifies how the value of a variable should be printed or displayed and SAS informats are the specification for how raw data should be read.
SAS on-demand provides the facility to use SAS software for data management and analytical uses to business, professionals, individual learners and instructors for free.
Sorting the data is always a resource-intensive operation. Therefore, using PROC SORT efficiently can save you both time and computing resources.
There are a number of options associated with PROC SORT that can be used not only to control the performance and capabilities of the procedure but also to the resulting data set.
RETAIN in SAS is used to “remember” values from previous observations. Variables that do not come from SAS data sets are, by default, set to a missing value during each iteration of the DATA step.
Variable conversions in SAS refer as to convert numeric to character variables or character to numeric variables. PUT: Converts numeric to character. The result is a character string the format […]
A majority of DATA steps use the SET statement. The primary function of the SET statement in SAS is to read observation from one or more SAS datasets. Properly using […]
