9to5sas SAS tutorials allow you to extend your knowledge in SAS. Our step by step SAS tutorials are easy to understand and follows the best coding practices. Don’t waste your time buying books that cover just the basics. These SAS tutorials contain examples, tips, and hacks to learn SAS faster.
The Proc PRINT procedure is used to print observations in a SAS data set using all or some of the variables, you can create dynamic reports with the help of proc print, which could include groups of the data and calculating totals and subtotals for numeric variables.
Automatic variables are added to the program data vector however are usually not output to the data set is created. The values of automatic variables are retained from one iteration of the DATA step to the subsequent, rather than setting it to a missing value.
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.
Ranking of variables is often necessary to analyze the performance or gain an insight on which are the values are on top or at the bottom and by using PROC RANK procedure, there is no need to write complex code using PROC SORT, MACRO calls and DATA STEPS to rank or decile these scores or values.
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.
COMPRESS function is basically used to compress/removes all the spaces/blanks or any other characters in a character string.
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.
