Custom prefixes in proc means?

[UniversitySas]

I know there is an autoname feature in proc means,

but I was wondering if there were a simple way to do something like:

proc means data = have;
        by date;
        var first1-first10 second1-second10;
    output out = table mean(first1-first10) = mean_(first1-first10);
Run;

I know the above code doesnt work, but instead of typing out

mean(first1-first10) = mean_first1 mean_first2 mean_first3.... 

Is there a quicker was to do this? Even if in a data step or proc sql?

I think /autoname wouldn't work here, because it would give me first1_mean, first2_mean ....

Thanks

Hi @UniversitySas 

I don't think that it is possible to achieve this in a PROC MEANS.

Here is an alternative approach:

proc means data = have;
        by date;
        var first1-first10 second1-second10;
    output out = table mean= / autoname;
run;

%let statistic = Mean; /*Select one the following: Min Max Sum StdDev Mean*/

proc sql noprint;
	select catt(name,"= &statistic._",scan(name,1,'_'))
	into: newnames separated by " "
	from dictionary.columns
 	where libname="WORK" and memname="TABLE" and find(name,"&statistic.")>0;
quit;

proc datasets lib=WORK nolist;
  modify TABLE;
    rename &newnames.;
quit;

Hope this helps.

You could rename them as this way.

data have;
date='xx';
input f1-f4;
cards;
1 2 3 4
2 3 4 5
3 4 5 6
4 5 6 7
;
proc summary data=have;
by date;
var f1-f4;
output out=want(rename=(f1-f4=mean_f1-mean_f4)) mean= ;
run;

[Astounding]

It should be straightforward:

proc summary data=have;
   var first1-first10 second1-second10;
   output out=want mean=mean_first1-mean_first10 mean_second1-mean_second10;
run;

This is untested code, so see if it works for your data.
