proc report define statement

rhaley1821 — Tue, 01 Dec 2020 06:29:05 GMT

Hi all,

I have been working on this problem for quite a while and cannot seem to figure out how to break up my proc report statements so as to display mean and std simultaneously for a numeric variable.

The table I wish to produce is:

	Average Pressures
	Systolic	Diastolic
Race Code	N	MEAN	STD	MEAN	STD
Asian	11	117.1	11.1	69.1	9.0
Black	83	123.3	15.3	74.0	7.0
Other Race	30	115.2	15.5	69.8	11.0
White	449	120.8	15.5	70.0	7.6
	573	120.8	15.4	70.6	7.8

My current code will not allow me to simultaneously display MEAN and STD:

PROC REPORT
DATA = hypanal.hypanalysis1 Split="/"
MISSING;
COLUMN RaceCd N ("Average Pressures"
("Systolic" SBP SBP) ("Diastolic" DBP DBP));
DEFINE RaceCd /group;
Define N / "N";
DEFINE SBP / ANALYSIS MEAN STD format=4.1 "MEAN" "STD";
DEFINE DBP / ANALYSIS MEAN STD format=4.1 "MEAN" "STD";
RBREAK AFTER / SUMMARIZE;
RUN;

the result is close, but only displays STD instead of STDs and MEANS:

Average Pressures Systolic DiastolicRace Code N MEANSTD MEANSTD MEANSTD MEANSTD

A	11	11.1	11.1	9.0	9.0
B	83	15.3	15.3	7.0	7.0
O	30	15.5	15.5	11.0	11.0
W	449	15.5	15.5	7.6	7.6
	573	15.4	15.4	7.8	7.8

I would appreciate any help!!

Thanks so much

You can only request one statistic or apply one column heading per Define statement.

One way that may do what you want is to use alias for the variable to request separate statistics. To do that you use "variable = aliasname" in the Columns statement and then use the Define with the aliasname

Something like:

PROC REPORT DATA = hypanal.hypanalysis1 Split="/"
  MISSING;
   COLUMN RaceCd N ("Pressures"
    ("Systolic" SBP=sysmean SBP=sysstd) ("Diastolic" DBP=dysmean DBP=dysstd));
   DEFINE RaceCd /group;
   Define N / "N";
   DEFINE sysmean / ANALYSIS MEAN  format=4.1 "MEAN" ;
   DEFINE sysstd / ANALYSIS  STD format=4.1  "STD";
   DEFINE dysmean / ANALYSIS MEAN STD format=4.1 "MEAN";
   DEFINE dysstd / ANALYSIS MEAN STD format=4.1  "STD";
   RBREAK AFTER / SUMMARIZE;
RUN;

I'm not sure that the column headings you are placing on the column statement with the parentheses will do exactly as you want but the define statements should work. You may want to include more decimals in the STD to be a bit more meaningful.

Hi:

A PROC REPORT use of alias as @ballardw suggested is the way to get what you want. Using SASHELP.HEART, which has DIASTOLIC and SYSTOLIC as variables, this is what it looks like, including headers:

I used BP_STATUS as the GROUP variable, but that was the major difference.

And, you can accomplish the same results using the comma operator with an analysis variable (essentially "crossing" or "nesting" statistics under an analysis variable, as shown in the code below:

And although that simplifies the COLUMN statement, it also has the limitation that MEAN and STD each get only 1 DEFINE statement, so you couldn't easily have one label for MEAN under SYSTOLIC and a separate label for MEAN under DIASTOLIC, for example.
