Study Notes
PROC PRINT Titles
- Titles in PROC PRINT are affected by subsequent title statements.
- Final output will display "The Top Line" for all PROC PRINT runs once it’s defined.
- The last title affects only the PROC PRINT that follows it.
Macro Variable Substitution
- Use
&symbol to reference macro variables in footnotes. - The correct syntax for substituting the Year variable is:
footnote "&year Sales";
DATA Step and Labels
- Labels assigned in a DATA step appear in PROC PRINT and PROC MEANS reports.
- The label for BatAvg will be visible in PROC MEANS when it is assigned in the DATA step.
BY Statement Functionality
- The BY statement organizes output by specified columns but does not sort data.
- Multiple columns can be used in a BY statement for grouping.
FREQ Procedure Misconceptions
- The NOPROCTITLE option does not exist as described and cannot be used to hide the title in PROC FREQ.
- ORDER=FREQ, PLOTS=, and OUT= options are valid and functional within PROC FREQ.
PROC FREQ for Variable Levels
- The PROC FREQ step that includes
nlevelsgenerates a summary of variable levels for specified columns. - Syntax:
proc freq data=sashelp.shoes nlevels; tables Region / nocum; run;
PROC FREQ Output Structure
- Specific PROC FREQ steps can generate cross-tabulated data, summarizing frequencies and percentages for selected variables.
- Example output includes frequencies of 'SUV' and 'Sedan' types across cylinder counts.
MEANS Procedure Insights
- The WAYS statement defines combinations of class variables in PROC MEANS but is not commonly updated.
- Output summary from OUT= option does not include automatic columns like COUNT or FREQ.
Input Table Requirements
- Input data for PROC MEANS does not need to be sorted based on CLASS statement variables.
- PROC MEANS can handle unsorted data, automatically managing groupings as specified.
Summary Output Creation in PROC MEANS
- Valid syntax for generating summary tables in PROC MEANS includes the OUT= option.
- Correct examples include:
output out=work.summary mean(Weight)=TotW;for summarizing mean values.
