SAS中有没有办法使用proc sql打印标签中变量的值？

Question

我有一种情况想将变量的值放在 SAS 的标签中。示例：Total_Days 的中位数是 2。我想将此值放在 Days_Median_Split 标签中。中位数随着数据的变化而不断变化，所以我想自动化它。

Phy_Activity Total_Days "Days_Median_Split: Number of Days with Median 2"
没有 0 0
没有 0 0
是 2 1
是 3 1
是 5 1

Sample Dataset

非常感谢！

Answer 1

* step 1 create data;
data have;
input Phy_Activity $ Total_Days Days_Median_Split;
datalines;
No 0 0
No 0 0
Yes 2 1
Yes 3 1 
Yes 5 1
run;

*step 2 sort data on Total_days;
proc sort data = have;
by Total_days;
run;

*step 3 get count of obs;
proc sql noprint;
select count(*) into: cnt
from have;quit;

* step 4 calulate median;
%let median = %sysevalf(&cnt/2 + .5);


*step 5 get median obsevation;
proc sql noprint;
select Total_days into: medianValue
from have
where monotonic()=&median;quit;

*step 6 create label;
data have;
set have;
label Days_Median_split = 'Days_Median_split: Number of Days with Median '  
%trim(&medianValue);
run;
