Question

我想知道是否有办法对多个类别进行频率调整，以便最终获得整体总记录，然后将子类别计算在其下面？

此刻你必须做2个频率然后2个转置，然后将数据设置在一起。以下是我通常会做到这一点的方法，但有没有办法在1个频率中完成？

Proc freq data = data noprint;
tables CATEGORY*SUBCATEGORY     / out = Data1;  
tables CATEGORY                 / out = Data2; 
Run;

Proc sort data = DATA1 out = DATA1; by CATEGORY SUBCATEGORY; Run;
Proc sort data = DATA2 out = DATA2; by CATEGORY; Run;

Proc transpose data = DATA1 out = DATA1;
  var COUNT;  
  by CATEGORY SUBCATEGORY;
Run;

Proc transpose data = DATA2 out = DATA2;
  var COUNT;  
  by CATEGORY;
Run;

data Final;
  set DATA1 DATA2;
run;

Answer 1

使用PROC SUMMARY而不是FREQ，TYPES语句使您可以选择要汇总的组。这只需要一步。

proc summary data=data;
class CATEGORY SUBCATEGORY;
types CATEGORY CATEGORY*SUBCATEGORY;
output out=want(drop=_type_ rename=(_freq_=COUNT));
run;

Proc Freq：按多个类别划分
