proc report - creating custom summary rows

js5 — Tue, 30 Jun 2020 11:58:03 GMT

Dear community,

I have been requested to provide a report in which mean, median, max, min and stdev are supposed to be shown in two rows: mean (std) and median(min-max) - and in this format. My existing code relies on having the results in a numeric column, which concatenated statistics are not:

%macro characteristics_sql_num(total=);
	select "MSRP" length=100 as Characteristics,
		"&summary_function" length=100 label=" " as Value,
		%if %length(&total) GT 0 %then &total as;
	Origin,
		&summary_function(MSRP) format=5.1 as result
		from sashelp.cars
		%if %length(&total) EQ 0 %then group by Origin;
%mend characteristics_sql_num;

%macro characteristics_num;
	%let summary_functions = mean std min median max;

	proc sql;
		create table cars_summary as

			%do i = 1 %to %sysfunc(countw(&summary_functions));
				%let summary_function = %scan(&summary_functions, &i);

				%if &i NE 1 %then
					union;

				%characteristics_sql_num
				union
				%characteristics_sql_num(total="Total")
			%end;
		;
%mend characteristics_num;

%characteristics_num

proc report data=cars_summary;
columns Characteristics Value Origin, result;
define Characteristics -- Value / group;
define Origin / across;
define result / " " format=best6.;
run;

I tried inserting the needed rows with break after and compute after, but this unfortunately does not work. Is there a way of generating the needed rows during proc report, or should I rather rebuild my macro to generate the needed concatenations already during proc sql? Thank you for your support in advance.

Not knowing how exactly the output needs to look (an example would help very much). Have a look at Proc TABULATE, it allows to have statistics on the row level.

See example below


proc tabulate data=sashelp.cars format=comma14.2;
  class origin;
  var msrp;
  table
    msrp="stats 1"*(mean std)
    msrp="stats 2"*(min median max)
    ,
    origin=" " all
  ;
run;

Thanks for responding! Switching to proc tabulate would unfortunately mean rewriting much of the available macros so I am afraid it is not feasible. It would probably be easier to adapt proc sql statements. Below is what I have vs what has been requested:

As I am using ODS excel, maybe there could be a way of putting in a formula which generates the needed format instead of handling it all in proc report?

Going with your Proc SQL approach, I would combine the stats already in the Proc SQL into a single var so Proc REPORT will just do the display.

Here is an example


proc sql;
  create table result as
  select
    "MSRP" as characteristic
    , origin
    , "mean (std)" as value
    , cats(mean(msrp), "(", std(msrp), ")") as cell
  from
    sashelp.cars
  group by
     origin

  union

  select
    "MSRP" as characteristic
    , origin
    , "median (range)" as value
    , cats(median(msrp), "(", catx(" ", min(msrp), max(msrp)), ")") as cell
  from
    sashelp.cars
  group by
    origin
   union
     select
    "MSRP" as characteristic
    , "Total"
    , "mean (std)" as value
    , cats(mean(msrp), "(", std(msrp), ")") as cell
  from
    sashelp.cars

  union

  select
    "MSRP" as characteristic
    , "Total"
    , "median (range)" as value
    , cats(median(msrp), "(", catx(" ", min(msrp), max(msrp)), ")") as cell
  from
    sashelp.cars
  ;
quit;

proc report data=result;
  column characteristic value Origin, cell;
  define characteristic / group ;
  define value / group ;
  define origin / across ;
  define cell / group " " style={textalign=right};
run;
