Proc Mean Significant Figures

[bc2017]

I'm aware when using the PROC Means procedure that you can round the entries in the resulting table to a certain number of decimal places but is there a way to round them to a certain number of significant figures. If there isn't, is there another procedure for generating summary statistics where this could be specified?

You can either output the data to a data set (see Examples 2 & 10 in the Documentation) or you could use PROC TABULATE for the same decimal places. However, significant digits are different and that's usually not a fixed rule, if I recall correctly.  So it may be easier to output to a data set and then implement your display rules and then use PROC PRINT or REPORT to display the output.

proc means data=sashelp.heart stackodsoutput;
   ods output summary=s;
run;
proc print label noobs;  format _numeric_ bestd8.7; run;

Look at the D and BestD formats.  This would be the easiest way to use them with PROC MEANS I think.

You could do it with the ODS:

proc means data=sashelp.class n mean std median clm STACKODSOUTPUT;
format age height weight best4.;
label weight="Weight (pounds)";
var age height weight;
ods output Summary=s;
run;

Proc sql;
select 
    variable,
    label,
    n,
    mean format=best5.,
    stdDev format=best6.,
    median format=best5.,
    lclm format=best5.,
    uclm format=best5.
from s;
quit;
