1. SAS tutorial 10/25

2. Overview
• PROC SUMMARY
• PROC SORT
• LABEL
• GOTO

3. SUMMARY & SORT

4. PROC SUMMARY
• Provides data summarization tools that
compute descriptive statistics for variables
across all observations or within groups of
observations.
• Similar to PROC MEANS

5. Syntax

6. Differences to MEANS
• Cannot do t-test
• Cannot calculate confidence limits
• Cannot estimate quantiles

7. Example 1

8. DATA creativity

9. Result

10. Use “BY” option

11. “Not sorted in ascending
sequence”

12. PROC SORT
• Orders SAS data set observations by the
values of one or more character or numeric
variables

19. LABEL & GOTO

20. GOTO
• Directs program execution immediately to the
statement label that is specified and, if
followed by a RETURN statement, returns
execution to the beginning of the DATA step.

21. (Statement) Label
• Specifies a statement label that identifies the
GOTO destination. The destination must be
within the same DATA step. You must specify
the label argument.

22. Example 3

23. • DATA info; • DATA info;
Input X @@; Input X @@;
If 1<=X<=5 then If X<1 or X>5 then do;
go to OK; X=3; count+1;
X=3; count+1; end;
OK:SUMX+X; SUMX+X;
Cards; Cards;
X1 X1’ SUMX
1 1 1
2 2 3
6 3 6
4 4 10
7 3 13
1 1 14

24. Return

Input X @@; Input X Y;
If 1<=X<=5 then go to If X<1 or X>5 then do;
OK;

Return;
